How to mine Bitcoins. Is it still worthwhile in ?

Nearly all mining farms are using the same hardware. Since the reward for finding a block is fixed, and the difficulty is adjusted based on total processing power working on finding blocks at any given time, then electricity is the only cost that is variable.

If you can find cheaper power than other miners, you can afford to either increase the size of your mining operation, or spend less on your mining for the same output. As previously mentioned, mining farms use a lot of electricity. How much they consume depends on how big their operation is. In total, it is estimated that all mining farms will use about 75 terrwat hours of electricity in the year That is roughly the equivalent to 15 times the yearly energy consumption of denmark.

Mining farms are located all over the world. We don't know where every mining farm in the world is, but we have some educated guesses.

Most of the mining has been and still is located in China. Why is so much Mining happening in China? The main advantages of mining in China are faster setup times and lower initial CapEx which, along with closer proximity to where ASICs are assembled, have driven industry growth there.

In this bonus chapter, we will learn about some of the most common terms associated with bitcoin mining. If you are thinking about mining at any level, understanding what these terms means will be crucial for you to get started.

The block reward is a fixed amount of Bitcoins that get rewarded to the miner or mining pool that finds a given block. A collection of individual miners who 'pool' their efforts or hashing power together and share the blockreward.

Miners create pools because it increases their chances of earning a block reward. Approximately every 4 years, the block reward gets cut in half. The first block reward ever mined was in and it it was for 50 Bitcoins. That block reward lasted for four years, where in , the first reward halving occured and it dropped to 25 Bitcoins.

In , a second halving occured where the reward was reduced to And as of the time of this writing, we are on the cusp of the third halving ETA May 11th , where the reward will be cut down to 6. You can find the most up to date estimation of exactly when the next halving will occur on our bitcoin block reward halving clock.

In plain english, that just means it is a chip designed to do one very specific kind of calculation. This is opposed to GPU mining, explained below. GPU mining is when you mine for Bitcoins or any cryptocurrency using a graphics card. This was one of the earliest forms of mining, but is no longer profitable due to the introduction of ASIC miners. Or it can refer to the total amount of hashing done on a chain by all miners put together - also known as "Net Hash".

Measured in Trillions, mining difficulty refers to how hard it is to find a block. The current level of difficulty on the Bitcoin blockchain is the primary reason why it is not profitable to mine for most people.

Bitcoin was designed to produce block reliably every 10 minutes. Because total hashing power or Net Hash is constantly changing, the difficulty of finding a block needs to adjust proportional to the amount of total hashing power on the network. In very simple terms, if you have four miners on the network, all with equal hashing power, and two stop mining, blocks would happen ever 20 minutes instead of every ten.

Therefore, the difficulty of finding blocks also needs to cut in half, so that blocks can continue to be found every 10 minutes. Difficulty adjustments happen every 2, blocks. This should mean that if a new block is added every 10 minutes, then a difficulty adjustment would occur every two weeks. The 10 minute block rule is just a goal though. Some blocks are added after more than 10 minutes. Some are added after less.

Its a law of averages and a lot if left up to chance. That doesn't mean that for the most part, blocks are added reliably every 10 minutes. A measurement of energy consumption per hour. Most ASIC miners will tell you how much energy they consume using this metric. As Bitcoin could easily replace PayPal, credit card companies, banks and the bureaucrats who regulate them all, it begs the question:. If only 21 million Bitcoins will ever be created, why has the issuance of Bitcoin not accelerated with the rising power of mining hardware?

Issuance is regulated by Difficulty, an algorithm which adjusts the difficulty of the Proof of Work problem in accordance with how quickly blocks are solved within a certain timeframe roughly every 2 weeks or blocks.

Difficulty rises and falls with deployed hashing power to keep the average time between blocks at around 10 minutes. For most of Bitcoin's history, the average block time has been about 9. Because the price is always rising, mining power does come onto the network at a fast speed which creates faster blocks.

However, for most of the block time has been around 10 minutes. This is because Bitcoin's price has remained steady for most of Satoshi designed Bitcoin such that the block reward, which miners automatically receive for solving a block, is halved every , blocks or roughly 4 years.

To successfully attack the Bitcoin network by creating blocks with a falsified transaction record, a dishonest miner would require the majority of mining power so as to maintain the longest chain. Pools and specialized hardware has unfortunately led to a centralization trend in Bitcoin mining. Bitcoin mining is certainly not perfect but possible improvements are always being suggested and considered.

Green sends 1 bitcoin to Red. A full node is a special, transaction-relaying wallet which maintains a current copy of the entire blockchain.

If there are no conflicts e. At this point, the transaction has not yet entered the Blockchain. Red would be taking a big risk by sending any goods to Green before the transaction is confirmed. So how do transactions get confirmed? This is where Miners enter the picture. Miners, like full nodes, maintain a complete copy of the blockchain and monitor the network for newly-announced transactions.

In either case, a miner then performs work in an attempt to fit all new, valid transactions into the current block. Acceptable blocks include a solution to a Proof of Work computational problem, known as a hash. The more computing power a miner controls, the higher their hashrate and the greater their odds of solving the current block. But why do miners invest in expensive computing hardware and race each other to solve blocks?

And what is a hash? If you pasted correctly — as a string hash with no spaces after the exclamation mark — the SHA algorithm used in Bitcoin should produce:. So, a hash is a way to verify any amount of data is accurate. To solve a block, miners modify non-transaction data in the current block such that their hash result begins with a certain number according to the current Difficulty , covered below of zeroes.

If other full nodes agree the block is valid, the new block is added to the blockchain and the entire process begins afresh. Red may now consider sending the goods to Green. You may have heard that Bitcoin transactions are irreversible, so why is it advised to await several confirmations? The answer is somewhat complex and requires a solid understanding of the above mining process:.

There are now two competing versions of the blockchain! Which blockchain prevails? Quite simply, the longest valid chain becomes the official version of events. A loses his mining reward and fees, which only exist on the invalidated A -chain. The more confirmations have passed, the safer a transaction is considered.

This is why what is known as '0-conf' or "0 confirmations" on the Bitcoin Cash blockchain is so dangerous. A company can claim to be a cloud mining company without any proof of actually owning any hardware. Note: If you do find a legitimate one, you'll need a wallet to receive payouts to. A secure hardware wallet like the Ledger Nano X is a good option. It depends what your goals are with cloud mining. If your goal is to obtain bitcoins, then there is really no reason to cloud mine or even mine at all.

If you find a legitimate cloud mining operation and you are making profit, you will very likely need to pay taxes on that profit. The best way to determine the taxes you owe is to use a crypto tax software. The reason there are so many cloud mining scams is because it is very easy for anyone in the world to setup a website. The company can act legit by sending initial payments to its customers. But after that it can just keep the already received payments for hash power and then make no further payments.

Two of the most famous cloud mining companies have already been exposed as scams: HashOcean and Bitcoin Cloud Services.

Even as recently as September of , cloud mining scams are stealing people's money. The SEC equivalent of the Phillipines just issued a warning to customers of Mining City to get out now and have told promoters of the company that they could go to jail for up to 21 years if they don't stop immedietely.

Old timers say, way back in mining bitcoins using just their personal computers were able to make a profit for several reasons. First, these miners already owned their systems, so equipment costs were effectively nil. They could change the settings on their computers to run more efficiently with less stress. Second, these were the days before professional bitcoin mining centers with massive computing power entered the game.

Early miners only had to compete with other individual miners on home computer systems. The competition was on even footing.

Even when electricity costs varied based on geographic region, the difference was not enough to deter individuals from mining. After ASICs came into play, the game changed. Individuals were now competing against powerful mining rigs that had more computing power. Mining profits were getting chipped away by expenses like purchasing new computing equipment, paying higher energy costs for running the new equipment, and the continued difficulty in mining.

As discussed above, the difficulty rate associated with mining bitcoin is variable and changes roughly every two weeks in order to maintain a stable production of verified blocks for the blockchain and, in turn, bitcoins introduced into circulation. The higher the difficulty rate, the less likely that an individual miner is to successfully be able to solve the hash problem and earn bitcoin. In recent years, the mining difficulty rate has skyrocketed.

When bitcoin was first launched, the difficulty was 1. As of May , it is more than 16 trillion. The Bitcoin network will be capped at 21 million total bitcoin. This has been a key stipulation of the entire ecosystem since it was founded, and the limit is put in place to attempt to control for supply of the cryptocurrency.

Currently, over 18 million bitcoin have been mined. As a way of controlling the introduction of new bitcoin into circulation, the network protocol halves the number of bitcoin rewarded to miners for successfully completing a block about every four years. In , this number was halved and the reward became In , it halved again to In May , the reward halved once again to 6. Bitcoin mining can still make sense and be profitable for some individuals. In an effort to stay competitive, some machines have adapted.

For example, some hardware allows users to alter settings to lower energy requirements, thus lowering overall costs. The variables needed to make this calculation are:. Profitability calculators differ slightly and some are more complex than others. Run your analysis several times using different price levels for both the cost of power and value of bitcoins.

Also, change the level of difficulty to see how that impacts the analysis. But there are still projects which are either just starting off, or have made the explicit decision to be supportive of CPU miners. The principle was soon broken for Bitcoin , though there are still coins that aim for some semblance.

CPU mining involves either using everyday computers or setting up components to make use of their capacity solely as mining devices.

The consensus in is that solo mining would be outdated but for the earliest stages of new coins, or those where the hashrate is extremely low due to almost no interest. Even if a CPU is used, solo mining, where a computer competes for the entire block reward, may be futile. The reason for this is that mining does not guarantee rewards, but is a game of chance. It may be possible for a solo miner to find a block header, but this may be an event that never repeats. Enter pool mining, which offers a higher percentage chance of winning a block reward.

A pool can consist of many types of miners, contributing their hashrate. When the pool is large enough, there is a higher chance of solving a block. The reward is then distributed proportionately among participants. Pool mining means your CPU will receive the chance for a fraction of a block reward, accruing over time to a certain stash of cryptocurrency.

Solving an entire block will yield a higher amount of coins, but will only happen based on astronomical probabilities, especially for mature networks. An Intel i7 Processor is consumer-available, and relatively advanced.

This processor, in the i7 modification, produces 2. At a similar power range, the Intel Core i7 K produces This mid-range hashing power can, in theory, be used for Monero or smaller coins. However, more advanced and powerful processors are also possibly joining the mining race.

With a retail price similar to the i7 range, this processor can start to achieve breakeven for Monero, depending on electricity prices. The best overall approach is to take stock of the mining power available, and whether it would be a good idea to use consumer electronics. From then onward, the list of relevant coins may shift, and some networks may become temporarily more difficult to mine. A curated list gives some examples of which coins are available for CPU mining, though each has different details and potential reward payout.

It is still difficult to estimate which coin is worth mining. Calculators constantly crop up, though with a warning that the favorable rates proposed may be misleading. Dedicating resources to a brand-new project is always a shot in the dark, and it is possible to mine in vain, accruing electricity costs and wearing down the processor. Market price risk remains the biggest factor in the final analysis.

Being able to sell the coins mined, or exchange them for other value, completes the analysis on whether the coin mining process has been profitable. Mining calculators usually calculate the profitability at the time of mining. In the past, miners have achieved enormous gains based on holding onto block rewards.

The boom in all altcoins in allowed small-scale miners to liquidate some of the rewards and end up with outlandish profits. But in , the decision to mine through CPU may be a game of pennies and dollars.

Curiously, the more hashrate is allocated, the more chance of breaking even and running a profitable operation. The Monero network turned highly competitive right after the fork, as apparently there were enough processor-owners to raise the hashrate.
