Plus it also removes any delays in payments that can otherwise take up to several weeks to clear. Subtracting the Cons of Bitcoin Bitcoin is great! Yeah, okay, we all know that already. But hold onto your hat for just one moment: In the interest of fair play, we want to highlight a few potential downsides. Gox, or other type of scam associated with this disruptive currency. Setting up a bitcoin wallet requires the installation of software on a computer or an app on a mobile device.
Want me to prove it? Still, there are a ton of people out there who have never heard of bitcoin. And even if they have — in one way or another — they may not have any interest in it. As long as there are no more educational efforts focusing on bit- coin on a consumer level, it will never gain mainstream adoption.
The technology side is pretty well covered for now, with tons of companies working on various implementations. The time has come to educate the average people on the street on the benefits of bitcoin and why it is in their best interest to get involved. Share it widely! Meeting up with bitcoin people If you can convince someone to try bitcoin, a domino effect often follows. Spreading the word about bitcoin on a level people can understand, comprehend, and tell to others is the key to gaining mass adoption in the future.
All hail, bitcoin! Unfortunately, information on bitcoin through conversation or presentation is not that easy to come by. There are several bitcoin conferences around the world every year, but ticket prices are too high for the average person to attend. Most of the sessions are later posted online, such as on YouTube later on though, which is a good thing. Keep your eyes peeled in the online community for further news.
These kinds of meetups are a great way to get to know people with a passion for bitcoin in or nearby a major city in your area. Plus, bitcoin meetups are free to attend as well. You can find out more about your local bitcoin group by heading over to www. Even if that place does not accept bitcoin, people will be more than happy to meet up. One of the things a lot of people really like about bitcoin meet- ups is that you can attend any of these events without any prior knowledge about bitcoin.
And one of the greatest moments during meetups happens when you can inform someone about all of the wonders digital currency and blockchain technology can help us achieve. Keep in mind these explanations do not have to be techni- cal at all for people to understand. Bitcoin can unite people from all different aspects of life, and once you find some common ground, it becomes easy to strike up a conversation. Once you find yourself in a position where you feel you have a natural way of explaining bitcoin and digital currency to people, you can always consider giving presentations on the subject.
There are usually plenty of opportunities to become a speaker. Granted, this is not something just anyone can do, as you have to feel comfortable speaking for larger audiences.
At bitcoin meetups, these crowds are anywhere from 5 to people, whereas confer- ences usually draw around — people. What might be even more important than just giving a presenta- tion is finding ways to engage your audience. Make sure they can interact with you, rather than just sit around and listen.
Once people become interested in the concept of bitcoin, they automatically want to learn more on the subject and the underly- ing technology. Trust One of the core elements of any kind of payment technology is trust. Given the number of headlines concerning bitcoin and scams, hacks, illegitimate services, and whatnot, there is a huge trust issue bitcoin needs to overcome. Rather than trusting the eco- nomic value of a bitcoin individually, it is more important to put your trust in the entire bitcoin network.
That includes all associ- ated services, companies, mining pools, and users in existence today, plus the ones that will be joining the network in the future. Bitcoin is still in its very early stages. It has been around for a little over six years at the time of writing. As is the case with any form of payment method, adoption is slow and faces a lot of adversity and scrutiny from competitors.
One thing people tend to forget is that bitcoin is not necessarily here to replace the current payment methods, but to show how things can be done differently in a more transparent manner. The reason for that is simple: It is convenient to use a bank account and bank card for storing and transferring money. Because that is how we were taught to use it. These days, there seems to be a shift in consumerism, as tradi- tional financial institutions want to dictate how we can spend money, and more importantly, how much we can spend.
Granted, in the Western world, consumers have other options to pay for goods and services. Bank cards, credit cards, and even bank transfers are frequently used to pay for just about anything, and cash is slowly becoming obsolete. This is one of the reasons why wire transfers take several days to reach their desti- nation, as every bank wants to take a cut of the fees for as long as they possibly can.
Other reasons include the inherent slowness of the banking clearing platforms such as the SWIFT network. That said, the customer is the victim of these delays, because late payments invoke more fees from the company waiting for its money. There are ways to speed up the process, but financial infrastructures are sticking to their old methods. Or to be more precise, there is one way to change that system, and that is by uniting and demanding change.
If the answer is yes, then bitcoin is worth checking out. No one is saying you need to put your full trust in bitcoin from the start, as there is a lot of information to sift through.
But if you are willing to keep an open mind to what bitcoin stands for and the point it is trying to get across, you can make a weighted decision on whether or not to put your trust in digital currencies.
Trusting modern technology Trust is something that is easily given by consumers these days. We blindly trust most of the services we use on a daily basis.
Social media platforms such as Facebook, Twitter, and Instagram hold a lot of our valuable data, all of which we are more than happy to give to them. Because we trust them enough with our data so that we can conveniently share it with friends and family.
But hardly anyone realizes what these companies can do with our data. When signing up for an account on any of these services, we accept their terms and conditions.
And those terms and conditions usually state that they can share the data with third parties for advertising and other purposes. Yet many who blindly trust Google, Apple, Facebook, and others end up taking a negative stance toward bitcoin.
That is the major difference between services we use that do not touch our finances, compared to services that are disrupting the financial world. Human nature makes us wary of everything that is new and brings change, as we do not like to change things all that much. Risk and volatility Bitcoin is a financial tool that carries risks just like any other pay- ment method or currency does.
However, with bitcoin, those risks are slightly different from traditional currencies and payments. Part of that comes in the form of a rather volatile price, but then again, any local currency fluctuates on a daily basis. Bitcoin and the underlying blockchain technology reduce a lot of the risks presented by traditional payment methods. There are no chargebacks, fraud is tough due to transparency, and the transac- tion fees are very low compared to credit cards, wire transfers, or remittance services.
The technology is still under development as we speak. We are still discovering potential use cases for block- chain technology. Even the best solutions and implementations may not be viable in the end, if nobody adopts them. But there is a flipside to that story as well.
Blockchain technology development shows lots of room for growth and creates jobs in the long run. From a technological standpoint, there is hardly any risk when investing in bitcoin itself.
Investing in a company that is work- ing on this new technology is a different matter altogether, but that principle is the same for any company you want to invest in.
Bitcoin company investments are not inherently riskier than investing in any other startup company. When it comes to speculating on the bitcoin price however, the story is a bit different. If you look at bitcoin from the perspective of an investment vehicle that will likely gain value, there are quite a few risks attached.
Speculating on price volatility is never a good idea, and bitcoin is proving to be rather volatile on a daily basis. What started out as a worth- less digital token quickly rose to something that actually held value, once the U.
Investors from all over have been buying up bitcoin, as they feel BTC is a safer method of storing and transferring value com- pared to precious metals or traditional payment methods.
But none of that was the intended use envisioned for bitcoin and blockchain technology: The main objec- tive was to cut out the middleman. It will take a few more years — at least — until merchants start pricing their goods and services in BTC value rather than using the conversion from a major currency.
And bitcoin can only gain mass adop- tion once we get more educational efforts underway in all regions of the world. Unfortunately, most of these education efforts are U. Key areas and emerging markets such as Africa, Asia, and even Australia have been overlooked in our opinion. Even though Australia may be an odd name on that shortlist, it is an interesting area for digital currency regardless. Asia and Africa are obvious choices, due to their remittance market potential, being under- banked, and technological prowess.
Despite all of that, bitcoin is usable as a payment method for virtu- ally anything, though you may have to jump through some hoops. Bitcoin debit cards are proving to be a great example, as they allow you to spend BTC wherever major credit cards are accepted. However, that will not push merchants to accept bitcoin all of a sudden, as it is just a regular card transaction to them.
And paying bills with bitcoin is possible as well, even though those services are limited to SEPA zones only for the time being. But both of these examples serve a different purpose. SEPA allows citizens to send bank transfers, denominated in euros, to other countries using the euro in a short span of time usually one to two business days.
SEPA is a forerunner of bitcoin — a case that has the potential to change the financial system as we know it. With mobile payments becoming more widespread, bitcoin is a very strong contender. In fact, mobile bitcoin wallets were avail- able even before most financial institutions unveiled their mobile apps. Whatever the future may hold, odds are bitcoin, or at least its blockchain technology, will play a major role in it. If things go according to plan, both the blockchain and bitcoin will be the most commonly used methods to transfer money across borders at zero fees.
In fact, bitcoin may become the best form of money ever invented. Investing in bitcoin is the most obvious answer, but there are other ways at your disposal as well. Not all of these methods cost very much money either, so read through and see which method suits you best.
Mining Bitcoins Bitcoin mining is a slightly misleading name. No one swings a pick- axe into rough stones in order to find additional bitcoins at least, I hope no one is trying that.
Bitcoin mining actually means adding more bitcoins to the digital currency ecosystem. There will be a total of 21 million bitcoin in circulation by , and there are roughly 15 million in existence at the time of this writing. How bitcoin mining works So, how do new bitcoins come into existence? All the additional bitcoins have to be generated through a computational process called mining. You do it by letting your computer hardware calcu- late complex mathematical equations, which can be done at any given time of the day.
Doing so enables you to become an integral part of the bitcoin network, not only by securing the network through your dedicated hardware, but also by generating more coins to put into circulation. To ensure that no more coins are generated every day than origi- nally intended, the mining process is linked to a difficulty rating. This rating goes up as more computational power joins the bitcoin network, and decreases when there are fewer miners competing for network blocks.
A short history of bitcoin mining Over the years, bitcoin mining has seen a tremendous evolution in terms of the required hardware to mine bitcoins.
Very little hard- ware was required when bitcoin launched in , as there was little to no interest in the project. But as more and more people caught wind of bitcoin and joined the network, the computational power increased exponentially. The mining difficulty parameter which determines how much computation power is required to solve the mathematical equations associated with generating bitcoins adjusted accordingly, in order to make sure new blocks on the bitcoin network were still ten minutes apart.
The reason for keeping bitcoin blocks ten minutes apart is to collect as many broadcasted bitcoin transactions into one block and validate these transactions at the same time. Because every computer has a CPU, and only a handful of people were mining bitcoins at that time, there was very little competition. In fact, most of the coins in the first few months were mined by Satoshi Nakamoto, who also gave away some coins to other people in order to allow testing of the bitcoin network.
Because a GPU — also called a video card — is specifically designed to solve complex mathemati- cal tasks, it is able to mine bitcoin more efficiently than a CPU. However, that performance is offset by a large increase in electric- ity use, as GPUs draw a lot more power from the wall compared to CPUs. This change was the first chapter in a long and storied bitcoin mining arms race.
Furthermore, any FPGA could mine nearly as fast as a GPU available at that time — while using far less electricity to complete the task of mining bitcoins.
This is a microchip designed specifically to mine bitcoin. But ASICs have a major downside as well: They are very power hungry, they make a lot of noise, and they generate a ton of heat. On the flipside, a bitcoin ASIC miner is vastly supe- rior to any other type of hardware in existence today and remains quite costly in some cases.
As these new devices started popping up, the need for electricity increased exponentially. As a result, mining bitcoins is extremely unprofitable in most parts of the world, unless you have access to cheap or free electricity. In most cases, the investment cost of bitcoin hardware, combined with the electricity costs, make it impossible to make a profit by mining at home.
But there is a solu- tion to that problem: Bitcoin cloud mining lets you mine bitcoin by purchasing mining power from a machine hosted in a different part of the world. Cloud mining has become somewhat popular in recent years. Most bitcoin cloud mining providers charge a daily or monthly fee to cover electricity costs. Cloud mining allows a user to start earning money directly, rather than waiting on the delivery of some fancy machine.
In the future, as with all computer advancements, microchips will be made smaller without sacrificing computational power. Engineers are trying to reduce the energy use of these microchips too. Making mining more energy efficient could lead to more profitability in additional parts of the world. The bitcoin price is volatile, which means it goes up and down on a regular basis. Experienced traders can profit by predicting price increases or decreases.
Successful bitcoin trades can earn you a decent amount of money over time, but be aware that things can go the other way as well. Always trade at your own risk, and only use money you can afford to lose. Day trading versus fiat Day trading is buying and selling financial instruments — such as bitcoin — within the same trading day. Using bitcoin allows you to trade in several different ways. The most obvious way of trading is exchanging bitcoins to and from any of the local currencies it can be traded against.
In most cases, people decide to go after the major fiat currency markets because they generate a lot more trading volume compared to smaller cur- rencies.
Bitcoin is well known for its volatile nature, so there are gains and losses to be made each and every day. Sometimes those losses or gains will be big, whereas other times they may not be. Alas, that is the life of day trading. Several trading platforms exist that let you speculate on the increase or decrease in bitcoin price versus a certain market — and they even accept bitcoin as payment. This is done in order to protect the merchant from any bitcoin price volatility that may occur, which is one of the reasons why so many shopkeepers are happy to join the digital currency train.
On the other hand, these conversions from bitcoin to fiat cur- rency also create a side effect, as there will be sell pressure across the major exchanges. Bitcoin payment processors need to liqui- date those bitcoin payments as soon as possible to pay the right amount to the merchant. As a result, there can be a few hefty BTC sell orders going through at certain times, which create a perfect opportunity to scoop up some slightly cheaper bitcoins.
Granted, the traditional factors influ- encing fiat currency also influence the bitcoin price in some way; of more danger is the way in which a new scam, or a major vote of confidence for or against bitcoin, can both shake up the price quite a bit. Yet there is not always a clear reason for a bitcoin price change either, as these things just happen.
Let me introduce altcoins — also known as alternative currencies. These are bitcoin clones, bitcoin rivals boo, hiss! If you do not like to trade or speculate on the bitcoin against fiat currency markets, you could trade against altcoins instead.
Altcoins seek to improve on the ideas bitcoin represents. Some people feel the need for more anonymity, whereas other develop- ers want to explore the boundaries of the underlying blockchain technology. Rather than submitting their ideas to the bitcoin devel- opers, they use the bitcoin code, change the name, make some minor tweaks, and launch it as a brand new digital currency. Over the years, only a dozen or so altcoins have managed to stay relevant over time, mostly thanks to a strong community and the integration of some unique features that have not made it to bit- coin core yet.
Nevertheless, none of these altcoin communities is as large or as supportive as the bitcoin community. And this is why so many day traders prefer to speculate on the altcoin markets, as there is a lot of room for quick profits and quick losses.
What this means is that developers create a lot of hype for their coin and promise unique and interesting features. As people find out about these promises, they are more eager to buy coins at a low price, which in turn pushes the price upward. Rather than pushing up the price by buying coins, some altcoin developers encourage community members to put down a lot of money for a valueless altcoin.
And once the price is high enough, these developers cash out, take their money, and work on a new coin for next week. There are many altcoins to go around, and most of them will never serve an actual purpose. However, if you can catch a few cheap coins before the price increases, there is a nice amount of profit to be made. Never become too greedy though, as prices can plummet even faster than they rise.
By accepting bitcoin as a payment method for your campaign, you can decentralize things even further and reach a global audience. Bitcoin provides businesses and individuals with a powerful tool to raise funds for an upcoming or existing project. When you convert the raised funds to fiat currency, you may be taxed on them, depending on the amount you receive.
When crowdfunding, never list a fake project or claim to do some- thing with the money you never intend to fulfill. Luckily for bitcoin enthusiasts, most crowdfunding projects so far have been legitimate, and most have delivered on their promises as well.
Depending on what type of project you list, it may take additional time to reach your goals, especially if it involves block- chain technology development. But not every project is using crowdfunding platforms for the right reasons. Some people view crowdfunding as a way to get some funds quickly, without ever having to pay it back. Even though most platforms implement security against misuse, there is always a minor chance of a project not delivering on the promises made.
But that has nothing to do with bitcoin per se — it can happen with any type of crowdfunding campaign. Simply look at how many people backed projects in Kickstarter and never received the item for which they pledged a certain amount. Check out www. Whenever you help crowdfund a bitcoin project, always determine whether you are entitled to some form of reward.
Crowdfunding is not the same as buying a share of a company or product at a cheaper rate. However, you should not partake in a crowd- funding campaign just for the reward. Most investors do so in the hopes of seeing the price per coin increase in the near future. Investors receive a share in said company and earn interest, paid out in recurring dividends. Both terms carry a slightly negative connotation in the world of bitcoin crowdfunding, because multiple false promises and scam projects have been associated with ICO and IPO promises.
That said, both are being used for legitimate purposes as well. Per certain amount invested, the user will receive X amount of tokens in return to use on the new platform once it has been launched. You are effectively offering your backers a tangible reward, even though it may not come in a physical form. Whether these digital tokens will gain value over time completely depends on the success of your proj- ect. But you are also incentivizing backers to spread the word about your crowdfunding campaign, which will go a long way in terms of developing a successful platform.
However, investors — both small and large — like nothing more than some sort of return on investment, prefer- ably sooner rather than later. And as a developer or project creator, you have responsibilities to live up to, including the distribution of these digital assets to the right people. Offering company shares and dividends Rather than offering potential investors digital assets, you could opt to grant them a share of your company or project in exchange for their money.
When taking this approach, you can ask for as much or as little per share as you personally like, but you have to ensure these shares represent some value. You can give your company shares value by paying weekly, monthly, or even quarterly dividends to shareholders. Once again, by doing so you incentivize potential investors to spread the word about your company or project, which is essentially an invaluable form of free marketing for whatever you are trying to achieve.
To make the offer even sweeter for potential investors, you can choose to pay out dividends in bitcoin. Even though these amounts will be very small in the early days, investors will start to see some form of return of their initial investment.
The same principle of paying dividends in bitcoin can be applied to potential investors who want to stick to traditional payment meth- ods, rather than buy bitcoin first.
Once they have sent you the des- ignated funds, you can still pay their dividends in bitcoin, in order to get them acquainted with the monetary aspect of this digital currency, assuming they are willing to agree to those terms. Holding Bitcoins for the Future Bitcoin attracts a lot of speculators from all over the world. Considering that the bitcoin price fluctuates constantly, you could gain a lot of money by buying bitcoin at a relatively low price in the hopes of earning a profit in the future.
Keeping in mind there will only be 21 million bitcoins in exis- tence by , it only seems logical that the price per bitcoin will increase over time. Whether or not that will actually be the case remains to be seen. In the early days of bitcoin, people would buy up cheap coins in the hopes of not only growing the network by giving out free BTC, but also because the price per coin would hopefully increase.
And that certainly fits the description of an investment vehicle. In the early days, every bitcoin being mined was virtually worthless, a trend that continued for quite some time until the network started to grow and more people shared an interest in bitcoin. As interest in bitcoin grew, the market price experienced a slow but steady uptrend between and As was to be expected, this price could not hold its ground, and the value started dropping again slowly after.
And in fact, some bitcoin enthusiasts do meet up on May 22 to enjoy a slice of pizza together while discussing everything related to bitcoin and the blockchain.
After that day, more and more people started to see the potential value of bit- coin, and investors scooped up as many coins as they could.
Quite an ambitious goal, especially when you take into consideration there will be a total of 21,, coins by Some financial experts saw this as the downfall of bitcoin, whereas others saw it as merely the begin- ning of a new era for the disruptive digital currency and perhaps of some currency speculators being shaken out of the market.
In simple financial terms, there was a bubble in the bitcoin price fol- lowed by a crash which has seen the price return to levels com- parable prior to the bubble. At the time of this writing, it remains unclear who was right. Hoarding your booty So many people own various amounts of bitcoin as an investment that a new problem has been created: Investors who bought bit- coin at a low — or very high — price are holding on to their bitcoin balance in the hopes of recouping their investment or making a profit.
With so many coins being kept out of active circulation for an unknown period of time, this raises concern regarding the future of bitcoin. As the price keeps drifting horizontally on the charts, rather than vertically, the sudden demand seems to have slowed down.
And bitcoin is no different in that regard. Strangely enough, hoarding also creates a positive side effect. Even so, there is still quite a scarcity, as not all of these coins are being spent or sold to other investors. That leaves interested parties with a smaller amount of coins to purchase, which should in turn, eventually, push the price up again. Depending on how much some of the original coin hoarders paid for their stash of bitcoin, it may take a long while until the BTC price settles at a point where they consider selling off some assets.
Regardless of how you look at the situation, hoarding is a problem in the bitcoin world. But keep in mind this digital currency is only six years old, and there is still a lot of time left to grow and gain more adoption on a global level. How that will affect the hoarding problem, as well as the views on bitcoin as an investment vehicle, remains to be seen.
The first thing to do is sign up to a bitcoin forum, and then read on. And as this forum has grown in popularity over the years, opportunities to make money have arisen as well. Forum signatures placed at the bottom of forum profiles and vis- ible on every post a user makes allow BitcoinTalk users to earn a small amount of bitcoins every time they make a constructive post or topic on the forum.
The person organizing this forum signature campaign keeps track of the number of posts you make during a week and pays the according amount at an agreed upon time. Or if you have a question you would like to see answered, the creation of a topic also counts as one post. Additionally, you may be rewarded for every constructive reply on your own topic. Secondly, some forum signature campaigns limit the number of posts you can make during a payout period. Any post over that amount is not rewarded.
One of the most important factors to determine whether or not a forum signature is right for you depends on your own user rank on BitcoinTalk. Members who are active and often participate in conversations will see their forum rank increase. The higher your forum user rank, the higher your forum signature payout per post will be.
Spamming the forum with clutter and short messages can lead to being banned and disqualified from the forum signature campaign. Earning through jobs Several platforms exist where you can find a job that pays in bit- coin. Whether you want to make a career out of working for bitcoin is a different matter entirely, but completing micro tasks is a great way to build a reputation and earn some money on the side.
Unfortunately, hardly any of these tasks pays a substantial amount, though some opportunities can lead to other doors being opened in the future. And those doors can lead to interesting job opportu- nities, even though those are more the exception than the rule. One thing to keep in mind when completing any sort of task in exchange for bitcoin is that you have to deal with legitimate people and companies only.
If a specific task needs to be completed for a certain company, your chances of getting paid are much higher compared to dealing with random individuals.
Additionally, there is no such thing as getting paid up front in the bitcoin world. Similar to how regular jobs work, you have to provide the service or goods first before you get paid.
There are usually no written contracts between both parties to warrant a payment, so tread carefully when jumping at an opportunity. Other than small tasks, there are always job opportunities from major bitcoin companies or from companies willing to explore the world of digital currency. Depending on your location, any form of bitcoin income might be subject to taxation.
This situation is different for every individual country. We advise you to check with your local government or tax revenue office to see whether bitcoin is taxable in your country. A faucet is a website that lets users claim a tiny amount of bitcoin in a certain time period, which can range anywhere from minutes to days.
In most cases, bitcoin faucet operators pay out of their own pocket for the first weeks or months until they can attract enough traffic and secure some advertising deals for their website.
As the name suggests, a bitcoin wallet is the place where you store all the relevant information for your bitcoins. Not only does a bit- coin wallet serve as a way to store your funds — similar to a bank account — it also allows you to send and receive funds. That bitcoin wallet address is the identification number by which you are known as a member of the bitcoin network.
It acts as your account number to send, receive, and store bitcoins. Unlocking Public and Private Keys There is more to a bitcoin wallet than just the address itself. It also contains the public and private key for each of your bitcoin addresses. Your bitcoin private key is a randomly generated string numbers and letters , allowing bitcoins to be spent. A private key is always mathematically related to the bitcoin wallet address, but is impossible to reverse engineer thanks to a strong encryption code base.
As mentioned, there is also a public key. This causes some confu- sion, as some people assume that a bitcoin wallet address and the public key are the same. That is not the case, but they are math- ematically related. A bitcoin wallet address is a hashed version of your public key. The public key is used to ensure you are the owner of an address that can receive funds. Besides these key pairs and a bitcoin wallet address, your bitcoin wallet also stores a separate log of all of your incoming and out- going transactions.
Every transaction linked to your address will be stored by the bitcoin wallet to give users an overview of their spending and receiving habits. Last but not least, a bitcoin wallet also stores your user prefer- ences. The Bitcoin Core client, for example, has very few preferences to tinker around with, making it less confusing for novice users to get the hang of it.
For computer users, that file is called wallet. Make sure to create one or multiple backups of this wallet. The bitcoin wallet software will let you import a wallet. More information on importing private keys and wallet. A bitcoin wallet, regardless of whether it is installed on a computer or mobile device, can contain more than one private key, all of which are saved in the wallet.
The following is a bitcoin private key in its hexadecimal format. This makes bitcoin one of the toughest encryption protocols to crack. However, seeing the value of a public key which also is the bitcoin address does not require you to know the private key at all. The public key associated with a wallet address is enough to receive bitcoins, and also to view the balance itself. But without the private key, there is no way to spend the balance associated with your bitcoin wallet address.
Should your private key ever be compromised, the only way to protect your bitcoin balance is by spending it to a different output that is secure a different wallet address for example. Getting Your Hands on a Bitcoin Wallet When you take paper money out of a bank machine, you need to put it somewhere — usually your wallet or your purse.
Surprise, surprise: Bitcoins also need to be stored somewhere, too, allowing you to access them when you want. Several variations of bitcoin wallets are available, such as software wallets, hardware wallets, paper wallets, and web wallets.
There are many different models for creating consen- sus because each blockchain is creating different kinds of entries.
Some block- chains are trading value, others are storing data, and others are securing systems and contracts. Bitcoin, for example, is trading the value of its token between members on its network. The tokens have a market value, so the requirements related to perfor- mance, scalability, consistency, threat model, and failure model will be higher. Bitcoin operates under the assumption that a malicious attacker may want to cor- rupt the history of trades in order to steal tokens.
Most blockchains operate under the premise that they will be attacked by outside forces or by users of the system. The expected threat and the degree of trust that the network has in the nodes that operate the blockchain will determine the type of consensus algorithm that they use to settle their ledger.
For example, Bitcoin and Ethereum expect a very high degree of threat and use a strong consensus algorithm called proof of work. There is no trust in the network. On the other end of the spectrum, blockchains that are used to record financial transactions between known parties can use a lighter and faster consensus. Their need for high-speed transactions is more important. Proof of work is too slow and costly for them to operate because of the comparatively few participants within the network and immediate finality need for each transaction.
The whole world has become obsessed with the ideas of moving money faster, incor- porating and governing in a distributed network, and building secure applications and hardware.
You can see many of these public blockchains by going to a cryptocurrency exchange. Blockchains are moving beyond the trading value market and are being incorpo- rated into all sorts of industries. Blockchains add a new trust layer that now makes working online secure in a way that was not possible beforehand. Current blockchain uses Most up-and-running blockchain applications revolve around moving money or other forms of value quickly and cheaply.
This includes trading public company stock, paying employees in other countries, and exchanging one currency for another. The U. Department of Homeland Security has been investigating blockchain software that secures Internet of Things IoT devices. IoT devices have also become more pervasive, and security has become more reliant on them. Hospital systems, self-driving cars, and safety systems are prime examples.
DAOs are another interesting blockchain innovation. This type of blockchain application represents a new way to organize and incorporate companies online. DAOs have been used to organize and invest funds via the Ethereum network.
Future blockchain applications Larger and longer-run blockchain projects that are being explored now include government-backed land record systems, identity, and international travel secu- rity applications. The possibilities of a blockchain-infused future have excited the imaginations of business people, governments, political groups, and humanitarians across the world.
Countries such as the UK, Singapore, and the United Arab Emirates see it as a way to cut cost, create new financial instruments, and keep clean records. They have active investments and initiatives exploring blockchain. Blockchains have laid a foundation where the need for trust has been taken out of the equation. Also, the infrastructure that enforces the rule if that trust is broken can be lighter. Much of society is built on trust and enforcement of rules. The social and economic implications of blockchain applications can be emotionally and politi- cally polarizing because blockchain will change how we structure value-based and socially based transactions.
This chapter is all about assessing blockchain technology and developing a project plan. It puts the following chapters about individual blockchain platforms and applications into context. I give you a few tools that help you out- line your project, predict obstacles, and overcome challenges. Some of this buzz just stems from the fluctuation in the value of cryptocur- rencies and the fear that blockchain technology will disrupt many industry and government functions.
None of these questions are simple, and the correct solutions can be difficult to ascertain. This section helps narrow down your options. Determining your needs Blockchains come in a lot of flavors. Mapping your needs to the best blockchain can be over- whelming.
Whenever I have lots of options and often conflicting needs, I like to utilize a weighted decision matrix. A weighted decision matrix is an excellent tool for evaluating the needs of a proj- ect and then mapping those needs to possible solutions. The key advantage of the matrix is to help you quantify and prioritize individual needs for your project and simplify decision making.
Weighted decision matrixes also prevent you from becoming overwhelmed by individual criteria. If done properly, this tool allows you to converge on single idea that is compatible with all your goals. To create a weighted decision matrix, follow these steps: 1. Brainstorm the key criteria or goals that your team needs to meet.
These are just a few to consider while evaluating the correct platform to use to meet your needs. Reduce the list of criteria to no more than ten items. Create a table in Microsoft Excel or a similar program. Enter the design criteria in the first column. Assign a relative weight to each criterion based on how important that objective is to the success of the project.
Add up the numbers for each objective and divide by the number of team members for a composite team weight. Make any needed adjustment to weights to make sure each criteria are weighted correctly. You now have a ranked list of criteria you need to meet to be suc- cessful with your blockchain project. Take the time to understand where you and your team would like to go and what the final objective is. For example, a goal might be to trade an asset with a partner company with no intermediary.
This is a big goal with many stakeholders. Build back to a small project that is a minimal viable use case for the technology that clearly articulates added value or savings for your company. Along the same lines as the earlier example, a smaller goal would be to build a private network that can exchange value between trusted parties.
Then build on that value. The next win might be building an instrument that is tradable on your new platform. Each step should demonstrate a small win and value created. Choosing a Solution There are three core types of blockchains: public networks like Bitcoin, permis- sioned networks such as Ripple, and private ones like Hijro.
This feature is particularly useful for auditing and proving compliance. They tend to be more secure and immutable then private or permissioned networks. Many of them utilize a cryptocurrency, but they can have a lower cost for applications that are built on top of them. This feature makes it easier to scale project and increase transaction volume. Permissioned networks can be very fast with low latency and have higher storage capacity over public networks.
They also have a low cost to run and can be built in an industrious weekend. Most private networks do not utilize a cryptocurrency and do not have the same immutability and security of decentralized networks. Storage capacity may be unlimited. There are also hybrids between these three core types of blockchains that seek to find the right balance of security, auditability, scalability, and data storage for applications built on top of them.
Drawing a blockchain decision tree Some of the decisions you face while working on a blockchain project within your organization can be difficult and challenging. A decision tree is a useful support tool that will help you uncover consequences, event outcomes, resource costs, and utility of developing a blockchain project. You can draw decision trees on paper or use a computer application. Here are the steps to create one for uncovering other challenges around your project: 1. Get a large sheet of paper.
Draw a square on the left side of the paper. Write a description of the core goal and criteria for your project in that square. Draw lines to the right of the square for each issue. Write a description of each issue along each line. Assign a probability value to encounter each issue. Brainstorm solutions for each issue. Write a description of each solution along each line.
Have teammates challenge and review all your issues and solutions before final- izing it. Making a plan At this point, you should have a clear understanding of your goals, obstacles, and what blockchain options you have available. Explain the project to key stakeholders and discuss its key components and foreseen outcomes. Write up a project plan. This is a living set of documents that will change over the life of your project.
Develop the performance measurements, scope statement, schedule, and cost baselines. Consider creating a risk management plan and a staffing plan. Get buy-in and define roles and responsibilities. Hold a kickoff meeting to begin the project. Go back and analyze your suc- cesses and failures.
This chapter helps you get started in the blockchain world. This chapter also helps you establish the basic crypto accounts that you need in later chapters. Diving into the Bitcoin Blockchain The Bitcoin blockchain is one of the largest and most powerful blockchains in the world.
It was designed primarily to send Bitcoin, the cryptocurrency. So, natu- rally, in order to create a message in the Bitcoin blockchain, you must send some Bitcoins from one account to another.
In this section, I explain how to build the message directly into the Bitcoin transaction. Embedding the data into the Bitcoin address ensures that it will be easily readable. You can do this by utilizing a Bitcoin vanity address. Think of a vanity address like a vanity license plate on a car.
Six-letter Bitcoin vanity addresses can be obtained for free; longer ones cost money. The longer the vanity address, the more costly it is. In this project, you create two Bitcoin wallets, add funds to one of them, obtain a vanity address, and send a little Bitcoin between your accounts.
If you already have a Bitcoin wallet with funds in it, you can skip the first section and use that wallet. Creating your first Bitcoin wallet A Bitcoin wallet address is composed of 32 unique characters. It allows you to send and receive Bitcoins. Your private key is a secret code associated with your Bitcoin address that lets you prove your ownership of the Bitcoins linked with the address.
Anyone with your private key can spend your Bitcoins, so never share it. Your first Bitcoin wallet needs to be linked to a credit card or bank account. It just takes a few minutes. The easiest Bitcoin wallet to use for this project is the Blockchain.
Fol- low these steps to create it: 1. Go to the Blockchain. Click Wallet. Click Create Your Wallet. Enter an email address and password. Generating a Bitcoin vanity address A Bitcoin vanity address is like having a personalized license plate for your car. A vanity address is optional, but a fun way to see your message in Bitcoin.
There are a several free ways to create a Bitcoin wallet vanity address. My favorite is BitcoinVanityGen. To create your vanity address using BitcoinVanityGen. Go to the BitcoinVanityGen. Enter six letters into the Type Letters field. Bitcoin only allows for small messages, and your vanity address will make up the content of your message, which you can easily read in Bitcoin.
Choose something cool because you can reuse your address whenever you want after it has been created. Click Generate. Click Email. Enter your email address. Click the link in the email from BitcoinVanityGen. Copy your address and private key, and keep them in a safe place. You will need your address and private key for the next section. Save your private key and a public key someplace safe.
Use your public key to receiving or send Bitcoins. You can share your public Bitcoin keys as much as you want. The private key is the actual keys to your Bit- coins. Cryptocurrency is unforgiving. Transferring your vanity address In this section, you transfer your vanity address to a wallet. Transferring it will allow you to manage your address, and send and receive Bitcoins easily.
Follow these steps to get started : 1. Log into your Blockchain. Click Settings and then click Addresses. Next to Imported Addresses, click Manage Addresses. Click Import Address, enter your private key, and click Import. Making an entry into the Bitcoin blockchain Now that you have two Bitcoin wallets, you can make an entry into the Bitcoin blockchain.
You do that by sending Bitcoins between your two wallets. It prompts you to enter the recipient. Enter a small amount of money that you would like to send, and then click Send.
You have forever engraved your message into the history of Bitcoin. If you enjoyed learning how to do this and want to take your knowledge further, you can access a helpful online tutorial on sending Bitcoin messages at www. A Bitcoin transaction normally takes ten minutes to be confirmed, but could take several hours.
The larger the value of the transaction, the longer you should wait. An unconfirmed transaction has not yet been included in the blockchain and is still reversible. Reading a blockchain entry in Bitcoin In the preceding section, I show you how to create a small permanent message in Bitcoin.
Data on the Bitcoin blockchain is not encrypted because the data needs to be confirmed by the nodes. This means it will be easy to find the message that you created in the last project. Enter your vanity address in the Search box and press Enter. The transaction page appears. Using Smart Contracts with Bitcoin A smart contract is autonomous software that can make financial decisions. In simple terms, a smart contract is a written contract that has been translated into code and build as complex if-then statements.
The contract can self-verify that conditions have been met to execute the contract. It does this by pulling trusted data from outside sources. Smart contracts can also self-execute by releasing payment data or other types of data. They can be built around many dif- ferent types of ideas and do not need to be financial in nature. Smart contracts can do all this while remaining tamper resistant from outside control.
Blockchain technology allowed smart contracts to come into existence because smart contracts offer the permanence and corrupt resistances that were once pro- vided only by paper, ink, and a trusted authority to enforce it all. Smart contracts are a revolution in how we conduct business. They ensure that a contract will be executed as it was written.
No outside enforcement is needed. The blockchain acts as the intermediary and enforcer. Smart contracts are a big deal because when machines start executing contracts, it becomes difficult or impossible to undo.
All smart contracts verify an external data feed to prove performance and release payment to the correct party. Legal contracts in our society rely on people to interpret what the parties entering into the contract meant. Computers at least so far can only understand code, not the intent of the parties. Many different types of smart contracts exist, and new ones are being invented every day. Follow these steps to build your first smart bond: 1.
Go to the SmartContract website www. Click Sign Up. The Sign Up page appears. Enter an email address and password and click Create an Account. SmartContract sends you an email with a confirmation link.
Click the link in the email sent to you by SmartContract to verify your account and log in. Click Create Contract. Click the Smart Bond tab see Figure Click the Create Contract button. Click the Smart Terms tab. Smart contracts verify an outside data feed to prove the performance of your contract and trigger the release of payment. Here you choose the conditions that will trigger your smart contract. Choose Performance Monitoring. Performance monitoring will look to see if an action has been taken outside of the contract.
In your case, this will be the movement of funds from one account to another. In the If Payment To field, enter one of your Bitcoin addresses created earlier in this chapter.
In the Is field, enter a small dollar amount that you would like to transfer from one Bitcoin address to the other. In the By Expiration Date field, enter a date a few days from now. This sets the time parameters that the contract will use to monitor outside sources. Click the Description tab see Figure In the Smart Contract Title field, enter a name for your contract.
Here you can also attach a legal document or other data, such as a image. Click the Attachments section. Smart contracts are new technology and can have hiccups.
Click Attach Documents. You can attach an image or a PDF. In the Address field, enter your email address to send yourself the contract. Click the Finalize Contract button. Now your contract will be monitoring the Bitcoin blockchain to monitor whether you send funds to the Bitcoin wallet address that you listed earlier.
Return to your Bitcoin wallets and send funds between the two wallets. Make sure to use the address and a little more than the amount that you listed on the contract in Steps 10 and The Bitcoin network will take a cut of the transaction, so add a little more to it so that it will meet the terms of the contract. Checking the status of your contract You can check the status of your contract at any time by following these steps: 1. Log into your SmartContract account at www.
Go to your Contract Dashboard. After your transaction has been completed, the contract will show as complete.
Your contract status is located below the Contract Dashboard. Give the Bitcoin network 10 to 15 minutes to process your transaction before checking the status of it. If you need a quick recap on coding before you dive in, I recommend Coding For Dummies by Nikhil Abraham Wiley for a great overview on coding for nontechnical people. In this section, you dive into building your first blockchain. You build it in two steps. The first step is to prepare your computer to create your private blockchain.
The second step is building your block- chain inside your Docker terminal. Preparing your computer You need to download some software on to your computer in order to try this blockchain project.
Start by downloading the Docker Toolbox. Go to www. Next, download GitHub Desktop. Follow these steps to complete the process: 1. Open GitHub Desktop. Return to your web browser and go to www. Click the Clone or Download button. Select the Open in Desktop option. The GitHub Desktop application will reopens. In the GitHub Desktop application, navigate to the project folder ethereum and click Clone. Cloning from GitHub copies the information you need to build your new block- chain. Follow the steps in the next section to get started building your private blockchain.
It gives you access to a virtual machine, cutting down the time required to set up and debug your system. Follow these steps: 1. The Quick Start Terminal should be located with your applications or on your desktop.
The Docker application launches a terminal you will use to build your blockchain. Change directories in the terminal to ethereum. The files you create making the new blockchain will go into the desktop file you made in the preceding section. You need to give a command to the terminal in order to change directories.
Now you can utilize the Ethereum—Docker files. Create one standalone Ethereum node by entering the following com- mand into your terminal: docker-compose -f docker-compose-standalone. Discover the beginning of blockchain technology with the Bitcoin blockchain. Clarify your knowledge of the Ethereum network, and expand your understanding of decentralized autonomous organizations and smart contracts. Identify the core concepts of the Ripple network and how it exchanges almost any type of value instantly.
Evaluate the Factom blockchain and its ability to secure data and systems. Dig into the high-speed DigiByte blockchain, and learn about some of the fun applications being built around blockchain technology. After reading this chapter, you may become hooked on this cool emerging technology. Read at your own peril. Bitcoin demonstrates the purest aspects of blockchain technology. Knowing the basics of how the Bitcoin blockchain operates will allow you to better understand all the other technology you encounter in this ecosystem.
In this chapter, I fill you in on the fundamentals of how the Bitcoin blockchain operates. I offer safety tips that will make your Bitcoin experience smoother and more successful. I also show you practical things you can start doing now with Bitcoin. In these pages, you find out how to mine the Bitcoin token, giving you a new way to get your hands on Bitcoins without buying them.
Finally, you discover how to transfer your tokens to paper wallets, and other practical ways to keep your tokens safe online. You can read the Bitcoin whitepaper at www. The author who first introduced Bitcoin in that whitepaper is an anonymous programmer or cohort working under the name of Satoshi Nakamoto. Nakamoto collaborated with many other open-source developers on Bitcoin until This individual or group has since stopped its involvement in the project and trans- ferred control to prominent Bitcoin core developers.
There have been many claims and theories concerning the identity of Nakamoto, but none of them have been confirmed as of this writing. Regardless, what Nakamoto created is an extraordinary peer-to-peer payment system that enables users to send Bitcoin, the value transfer token, directly and without an intermediary to hold the two parties accountable.
The network itself acts as the intermediary by verifying the transactions and assuring that no one tries to cheat the system by spending Bitcoins twice. Many Bitcoin enthusiasts feel that blockchain technology is the missing piece that will allow societies to operate entirely online because it reframes trust by recording relevant informa- tion in a public space that cannot be removed and can always be referenced mak- ing deception more difficult.
Blockchains mix many old technologies that society has been using for thousands of years in new ways. For example, cryptography and payment are merged to cre- ate cryptocurrency. Cryptography is the art of secure communication under the eye of third parties. Payment through a token that represents values is also something humans have been doing for a very long time, but when merged, it creates cryp- tocurrencies and becomes something entirely new.
Cryptocurrency lets you take the concept of money and move it online with the ability to trade value securely through a token.
Blockchains also incorporate hashing transforming data of any size into short, fixed-length values. Ultimately, blockchains are ledgers, which society has been using for thousands of years to keep financial accounts. When all these old models are merged and facili- tated online in a distributed database, they become revolutionary.
Bitcoin was designed primarily to send the Bitcoin cryptocurrency. But very quickly, the creators realized that it had a much larger potential. With that in mind, they architected the blockchain of Bitcoin to be able to record more than the data concerning the movement of the token.
The Bitcoin blockchain is the oldest, and one of the largest, blockchains in the world. The protocol is creating and securing the blockchain. In very simple terms, the blockchain is a public ledger of all transactions in the Bitcoin network, and the nodes are computers that are recording entries into that ledger. The Bitcoin protocol is the rules that govern this system.
Nodes safeguard the network by mining for the cryptocurrency Bitcoin. New Bit- coins are created as a reward for processing transactions and recording them inside the blockchain. Nodes also earn a small fee for confirming transactions. Anyone can run the Bitcoin protocol and mine the token. The primary thing that makes Bitcoin a secure system is the large number of independent nodes that are globally distributed. The most successful miners have robust systems that can outperform slower miners.
Early in its history, you could run the Bitcoin protocol and earn Bitcoins on a desktop computer. Now, in order to have any hope of ever receiving Bitcoins, you need to purchase expensive specialized equipment or use a cloud service.
In order to create a message in the Bitcoin blockchain, you have to send some Bitcoin from one account to another. When you send a transaction in Bitcoin, the message is broadcast across the whole network. This feature makes it imperative that you always choose your message wisely and never broadcast sensitive information.
So, Bitcoin requires that you keep your communications very short. The current limit is just 40 characters. These limitations are hard-coded into the Bitcoin protocol and help ensure that the net- work stays decentralized. Larger blocks would impose hardships on the miners and might push out small operations. Bitcoin has built-in limitations that prevent it from handling the global volume of mone- tary transactions.
It is also being used to secure other types of data and systems. The demand to use the secure Bitcoin ledger is high.
This difficulty is referred to as Bitcoin bloat, and it has slowed down the network and increased the cost of transactions. At this point, most blockchain developers are only experimenting with expanding the utility of the Bitcoin blockchain. Most are not at a point where they need to scale up their prototypes and concepts so that the Bitcoin blockchain can handle their request.
Other new blockchain technologies have also helped bring down the pressure on Bitcoin and given developers cheaper options to secure data.
Dubbed the Bitcoin Civil War or the block size limit debate, the general conflict is between keeping Bitcoin core as it is and enlarging the functionality of the software. This conflict appears simple, but the repercussions are enormous. Beyond the internal conflict, Bitcoin is also under intense scrutiny from the outside. The decentralized nature of Bitcoin that may displace central authorities made it a target for regulators. Bitcoin is also favored by people who want to purchase illicit items anony- mously or move money from a controlled economy to a noncontrolled economy, bypassing governmental controls.
All these factors have given Bitcoin a bad rap and drawn the judgment of society. Entrepreneurs that wanted to capitalize on the technol- ogy of Bitcoin rebranded it. The change in terminology was used to differentiate the software structure of Bitcoin and other cryptocurrencies. Software that used the struc- ture of cryptocurrencies began being called blockchain. The shift to deemphasize the controversial tokens and highlight the structure of cryptocurrencies changed both gov- ernment and commercial views of Bitcoin from fear to excitement.
Bitcoin is a living and ever-changing system. The Bitcoin core development com- munity is actively seeking ways to improve the system by making it stronger and faster. Anyone can contribute to the Bitcoin protocol by engaging on its GitHub page www. However, there is a small community of domi- nant core developers of Bitcoin. There has never been a successful attack on the Bitcoin blockchain that resulted in stolen Bitcoins. However, many central systems that use Bitcoin have been hacked.
And wallets and Bitcoin exchanges are often hacked due to inadequate security. The Bitcoin community has fought back by developing elegant solutions to keep their coins safe, including wallet encryption, multiple signatures, offline wallets, paper wallets, and hardware wallets, just to name a few. Hackers breach networks and hold them hostage until payment is made to them.
Hospitals and schools have been victims of these types of attacks. However, unlike cash, which was favored by thieves in the past, Bitcoin always leaves a trail in the blockchain that investigators can follow. Bitcoin is the opposite of a pyramid scheme from the point of view of Bitcoin miners.
The Bitcoin protocol is designed like a cannibalistic arms race. Every additional miner prompts the protocol to increase the difficulty of mining. From a social point of view, Bitcoin is a pure market.
The price of Bitcoins fluctuates based on market supply, demand, and perceived value. Bitcoin has a limit to the number of tokens it will release. That number is hard-coded at 21 million. The estimated date of Bitcoin issuing its last coin is believed to be in the year Here are some examples:. You know how your everyday, government-based currency is reserved in banks?
And that you need an ATM or a connection to a bank to get more of it or transfer it to other people? Well, with cryptocurrencies, you may be able to get rid of banks and other centralized middlemen altogether. Instead, every computer in the network confirms the transactions.
Before getting into the nitty-gritty of cryptocurrencies, you need to understand the definition of money itself. In order for money to be valuable, it must have a number of characteristics, such as the following:.
Of course, in the old days, when you traded your chicken for shoes, the values of the exchanged materials were inherent to their nature. But when coins, cash, and credit cards came into play, the definition of money and, more importantly, the trust model of money changed. Another key change in money has been its ease of transaction. The hassle of carrying a ton of gold bars from one country to another was one of the main reasons cash was invented.
Then, when people got even lazier, credit cards were invented. But credit cards carry the money that your government controls. Fiat is described as a legal tender like coins and banknotes that have value only because the government says so.
The first ever cryptocurrency was drumroll please Bitcoin! You probably have heard of Bitcoin more than any other thing in the crypto industry. Bitcoin was the first product of the first blockchain developed by some anonymous entity who went by the name Satoshi Nakamoto. Bitcoin was the first established cryptocurrency, but many attempts at creating digital currencies occurred years before Bitcoin was formally introduced.
Cryptocurrencies like Bitcoin are created through a process called mining. Very different than mining ore, mining cryptocurrencies involves powerful computers solving complicated problems. Bitcoin remained the only cryptocurrency until But as of the time of writing, more than 1, cryptocurrencies are available, and the number is expected to increase in the future.
Still not convinced that cryptocurrencies or any other sort of decentralized money are a better solution than traditional government-based money? Here are a number of solutions that cryptocurrencies may be able to provide through their decentralized nature:. Their cash becomes barely as valuable as rolls of toilet paper. Most cryptocurrencies have a limited, set amount of coins available. When all those coins are in circulation, a central entity or the company behind the blockchain has no easy way to simply create more coins or add on to its supply.
During the Bitcoin hype, a lot of misconceptions about the whole industry started to circulate. These myths may have played a role in the cryptocurrency crash that followed the surge. The important thing to remember is that both the blockchain technology and its byproduct, the cryptocurrency market, are still in their infancy, and things are rapidly changing.
Just like anything else in life, cryptocurrencies come with their own baggage of risk. Whether you trade cryptos, invest in them, or simply hold on to them for the future, you must assess and understand the risks beforehand. Some of the most talked-about cryptocurrency risks include their volatility and lack of regulation. Volatility got especially out of hand in , when the price of most major cryptocurrencies, including Bitcoin, skyrocketed above 1, percent and then came crashing down.
However, as the cryptocurrency hype has calmed down, the price fluctuations have become more predictable and followed similar patterns of stocks and other financial assets.
Regulations are another major topic in the industry. The funny thing is that both lack of regulation and exposure to regulations can turn into risk events for cryptocurrency investors. Cryptocurrencies are here to make transactions easier and faster. But before you take advantage of these benefits, you must gear up with crypto gadgets, discover where you can get your hands on different cryptocurrencies, and get to know the cryptocurrency community.
Some of the essentials include cryptocurrency wallets and exchanges. Some cryptocurrency wallets, which hold your purchased cryptos, are similar to digital payment services like Apple Pay and PayPal. Get the most secure type of wallet, such as hardware or paper wallets, instead of using the convenient online ones.
