Some people just never learn. I thought after the FTX crash people would actually stop keeping their coins on exchanges. At least most of them.
Statistics shows that less and less coins seem to be stored at exchanges, so at least those that have the most skin in the game are learning their lesson and storing those coins on their own, however it is very difficult for most people to forfeit the convenience that exchanges provide, since they are leaving the responsibility to store their coins to a third party, and since this is what they have done with banks all their lives, they do not see the problem to do this with their bitcoin as well, a mistaken posture without a doubt, but if they do not want to listen despite the repeated warnings we give, there is not much else we can do.
