Bitcoin is like gold in many ways. Like gold, Bitcoin cannot simply be created arbitrarily. Gold must be mined out of the ground, and Bitcoin must be mined via digital means. Linked with this process is the stipulation set forth by the founders of Bitcoin that, like gold, it have a limited and finite supply. In fact, there are only 21 million Bitcoins that can be mined in total. Once miners have unlocked this many Bitcoins, the planet's supply will essentially be tapped out, (unless Bitcoin's protocol is changed to allow for a larger supply). Supporters of Bitcoin say that, like gold, the fixed supply of the currency means that banks are kept in check and not allowed to arbitrarily issue fiduciary media. But what will happen when the global supply of Bitcoin reaches its limit?🤔
