Primary Market Overview: Circulating Supply and Total Supply
· Total supply generally refers to all tokens that have been created, minus those that have been burned. It includes tokens that are not yet in circulation.
· Maximum supply refers to the maximum number of tokens that can exist under the protocol rules. Bitcoin’s maximum supply is 21 million.
The maximum supply of $BTC is hardcoded at 21 million, and the amount already mined is getting closer to this limit.
