Bitcoin's (BTC) total supply is capped at 21 million coins, a fundamental aspect of its design. This limit was set by Bitcoin's creator, Satoshi Nakamoto, to prevent inflation and maintain the cryptocurrency's value. The 21 million cap ensures scarcity, similar to precious metals like gold. As of now, over 19.5 million Bitcoins have been mined, with the remaining coins to be released through the mining process. The limited supply contributes to Bitcoin's appeal as a store of value and a hedge against inflation. The deflationary nature of Bitcoin, due to its capped supply, contrasts with traditional fiat currencies, which can be subject to inflationary pressures. This unique monetary policy has been a key factor in Bitcoin's popularity and its potential as a long-term store of value. The 21 million cap is a cornerstone of Bitcoin's economic model.
