Bitcoin Transactions Per Day
Bitcoin mining is designed to be similar to gold mining in many ways. Bitcoin mining and gold mining are both energy intensive, and both have the potential to generate a handsome monetary reward. Bitcoin mining is a highly complex computing process that uses complicated computer code to create a secure cryptographic system. Similar to the secret codes used by governments and spies, the cryptography used for mining generates Bitcoin, facilitates Bitcoin transactions, and tracks asset ownership of the cryptocurrency. Bitcoin mining supports the Bitcoin database, which is called the blockchain. Bitcoin miners are not people with picks and shovels, but rather owners of sophisticated computing equipment. Bitcoin miners compete to be the first to verify Bitcoin transactions, and earn rewards paid in Bitcoin.
