The third option is Bitcoin mining and most players do not use this because it is a complex process that requires extensive skillsets in computer programming and algorithms. Bitcoin miners are specialists who create Bitcoins by adding the records of transactions to what is called a blockchain. A blockchain is a public ledger online that is available for free.
