Nowadays, mining is so power demanding, that specifically designated chips are being produced for it. In this pool they seek the solution together with the other miners and then divide the given reward on the basis of the executed work number of trials. They do not have to wait years to earn money for the electricity bill, but they get a lower, but regular income which covers their computer runtime elecricity and Internet costs. On the basis of the above mentioned, it can be said that the price of the bitcoin depends on the electricity prices and that the part of bitcoin we own is a share on the solution of a mathematical equation.

Apart from the reward for the newly mined block, the miner receives also the fees from all the newly included transactions into the block.

In case of a big number of transactions the size of the block is limited and not always all the new transactions accommodate into it then the fee motivates the miner to record transactions with the highest fees into the new block.

You may set your fee when you create your transaction. With the fee you regulate the priority of your transaction. The reward for the miner is set by bitcoin protocol programmed regulations. At the start of this currency, the reward for a new block was 50 BTC. This reward gets reduced by half around every 4 years. It is calculated that in total there will only be 21 million BTC around Then, the rewards for the miners shall only be the transaction fees and not newly generated bitcoins.

From the above mentioned, it is clear that the bitcoin is rather a deflationary currency. The classic currencies are usually inflationary. It is questionable what impact will the deflationary feature have on the bitcoin economy why should I spend my bitcoins today, when tomorrow they will be worth more. Bitcoins from the address beginning with number 1 may be sent using only one key.

Bitcoins from the address beginning with number 3 may be sent using a key combination. For example, the transaction must be signed by at least 2 keys out of 3. This enables safe collective control of the funds when each key is owned by someone else. It is possible and it happens. The information regarding a new block is sent by the miner to all of his peers around and these send it further. It is possible that before this information gets from one side of the network to the other, another miner finds a competitive solution on the other side.

It has already been said that each block contains a link hash of the previous block. Which hash are the miners going to use for the next new block? They will use either the one which is most convenient for them from which they get more fees — if they were the ones to mine it or the one which creates a chain with the most work done.

The biggest count of 0 in hashes of all blocks difficulty. The number of confirmations represents the distance in the number of blocks in the blockchain from the block, in which the transaction was included. This distance gives you degree of certainity that the bitcoins have been transferred.

When there are 0 confirmations it is not sure the transaction is really going to be included into a block. The bitcoins become yours only when the transaction gets included into the blockchain.

We can say that those who control bitcoin are:. Nowadays, deterministic wallets are actually a standard which enable an easier storage and backup of keys and a better anonymity. Although bitcoin enables a certain level of anonymity nobody knows who owns which bitcoins , it is not completely ideal.

In case you are using one key for all your funds and you pay for a beer at a pub, then the pubkeeper can check your balance in the blockchain on the address you sent the bitcoins from. To prevent this from happening, it is recommended to use more wallets keys in which your bitcoins are divided. The ideal case is when a new wallet is generated with every payment new key — also called change address , the remaining part of your wallet shall be transferred to this new wallet. Like this, you can get even a keys in a short period of time.

The loss of any of the keys to which your bitcoins are bound to, may cause the loss of these bitcoins. It is impossible to expect that user will backup his keys with each payment. The deterministic wallet solves this problem. After the installation, the wallet generates a so called master key, from which one may deterministically calculate other private keys. It is therefore necessary to backup only this master key.

The backup of the master key is usually made by writing down 12 or 24 words on paper. Whenever in the future a wallet gets lost broken harddisk or stolen phone the backed up master key enables to re-calculate all the private keys and to get to all your bitcoins.
