Well, just use Gold as an example : Gold is a scarce commodity and it is mined. The Bitcoin miners are running software that
are looking for these bitcoins. {over simplified} Once they put the work in, they get rewarded for their efforts with bitcoins
that are released from a pre-determined protocol. {they process the transactions and validate them on a database that are
stored on a decentralized Blockchain} ...There will only be 21 000 000 bitcoins released, so it is just as scarce as Gold.
