Do actually exist a website, page (even a section in Bscscan, Etherscan) where I can track the supply of a certain token and figure out how it changed during the existence of the token?
I mean like the "historical data" section in Coinmarketcap.
You can see that on coinmarket and coingecko, thought it might not updated but at least you have the figures. If you want a more accurate total number of supply, then go to the contract address and you’ll see how much supply already out in the market, historically its hard to find that.
