Miners, Who Are They?

In the world of Bitcoin, the miners are the key figure of any transactions procedure.

To describe them in one sentence: they confirm the transactions between Bitcoin users.

Mining is the mathematical race using computers. 

Specifically, the mining is the making computer to do the mathematical calculations for the Bitcoin network to confirm transactions (bitcoin.org). 

Not all Bitcoin users are Miners—only a small portion of them. The nature of the mathematical problems set the fairness of any transactions. 

 Miners confirm the transactions, and for their service they get some amount of Bitcoin (about 25 Bitcoin per transaction).
