Why Bitcoin Has a 21 Million Supply Cap ?
When Satoshi Nakamoto created Bitcoin, he hard-coded a maximum supply of 21 million coins into the protocol, The reason was philosophical as much as technical, he wanted Bitcoin to behave more like gold than like paper money.
Traditional currencies like the dollar can be printed in unlimited amounts by central banks.
When more money is printed, each existing dollar loses a little value over time, that's inflation. Satoshi wanted Bitcoin to be the opposite of that, a currency where no government or institution could just create more out of thin air.
By capping the supply, Bitcoin becomes scarce by design. Scarcity is what gives things like gold or diamonds their value. If there were an infinite supply of gold, it wouldn't be worth much. The same logic applies here, the harder something is to get, and the more people want it, the more valuable it becomes.
The 21 million number itself wasn't derived from some deep mathematical formula. It was a deliberate design choice to ensure that even the smallest unit of Bitcoin, called a satoshi, would be enough to handle global transaction volume if Bitcoin ever reached mass adoption.
