I don’t just know why some people do take the risk of leaving their coin on exchange, we all have seen different exchanges that failed previously, lots of exchanges have been hacked before, I just dont know why some people are not learning from things that happened previously
Laziness and ignorance, as simple as that. Luckily for CEXes, theere is a constant influx of new users that no very little about all the dangers of using centralized exchanges to store their crypto.
Those who keep funds on exchange are those who is trading on a regular basis
That would be great if those were the only one who are keeping their crypto on exchanges. In reality, biggest "problem" are those who are using centralized exchanges for a long term hodl, as they mistakenly see exchanages as a sort of bank while in fact they are much worse than them and offer bascially no protection at all.
