Seeing content like this really makes me laugh to death!
This brother said that a certain exchange issued 620,000 bitcoins, but the exchange actually only has 40,000, and then inferred that there are not just 21 million bitcoins!
Brother, the numbers in your account at a centralized exchange can be changed at will; many users' bitcoins and ethers at centralized exchanges are stored in one wallet. Only when you transfer money out will this wallet actually be called; otherwise, you see that transfers between Cex users have no fees. Why is that?
Of course, in the past, exchanges often used users' coins to manipulate the market and then bought them back. The number of users' coins did not decrease, only the assets decreased. This is how Cex makes money.
So there are many problems with Cex at the moment. This is just one of them, and it is also why I have always emphasized that Dex will eventually replace Cex.
