One of the core features of Bitcoin (making it very different from Ethereum) is its limited supply of 21 million. According to blockchain.com, the total number of bitcoin that have been mined and are currently in circulation on the network is 18.5 million, or 88% of the 21 million. There are only 2,508,012 (2.5 million) bitcoin left to be mined, and Bitcoin already has a market cap of $200 billion with over 54 million wallets. The importance of a limited supply has never been more apparent than now, as central banks around the world ramp up their money printing to increase inflation and encourage spending. Not only does Bitcoin have deflationary features in its fixed supply, its value continues to rise as institutions like Grayscale (who owns 2.4% of all Bitcoin) keep buying pressure high.
