How Bitcoin Mining Works

Where do bitcoins come from? 
With paper money, a government decides when to print and distribute money. Bitcoin doesn't have a central government. With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.

The first cryptocurrency miner to crack the code is rewarded by being able to authorize the transaction, and in return for the service provided, cryptominers earn small amounts of cryptocurrency of their own. In order to be competitive with other cryptominers, though, a cryptocurrency miner needs a computer with specialized hardware.

Cryptocurrency mining, or cryptomining, is a process in which transactions for various forms of cryptocurrency are verified and added to the blockchain digital ledger. Also known as cryptocoin mining, altcoin mining, or Bitcoin mining (for the most popular form of cryptocurrency, Bitcoin), cryptocurrency mining has increased both as a topic and activity as cryptocurrency usage itself has grown exponentially in the last few years.
