What is Bitcoin Mining?
Bitcoin mining uses computing processing power to run SHA256 double round hash verification processes to validate Bitcoin transactions and provide the requisite security for the public ledger of the Bitcoin network. Computing power or the speed you mine Bitcoins at is measured in hashes per second.
To earn Bitcoin, the network awards your miners with Bitcoin based on your computing power. The more miners you have and the more computing power you have ,the more Bitcoin you can earn.
