Why do different data websites show different circulating supplies for the same coin?
Here’s how I understand it: when a coin’s circulating supply is only a small fraction of its maximum supply, a substantial amount may still be released later. In that case, it’s worth checking the unlock schedule too.
Circulating supply refers to the number of tokens currently in circulation on the market, excluding tokens that are still locked.
My current habit is to verify the circulating supply against the project’s official tokenomics information, since data websites sometimes lag behind.
The maximum supply of $BTC is fixed at 21 million coins, and the amount mined is getting closer and closer to that limit.
