It's everyone's choices that led us to this point. Stop leaving money on exchanges and using them as a personal wallet and the problem is solved. It's not the idea of dex vs cex, it's really how people utilize them. Put money on, trade, take money off to wallet where only you control the keys. Boom problem solved
I really wonder if there are still such people keeping money on exchanges, especially after all the latest news about coins delist, exchanges blocks, etc. My rule from the very beginning was to choose the trusted wallet and keep everything there.
There are tens of millions of such people. Understand that 90% of people are very stupid and they are just too lazy to create a wallet and store funds on the wallet, it is easier for them to store everything on the exchange. This is also the fear of responsibility. Many people just want to shift the responsibility to the exchanges, and in case they lose their funds, they will have someone to blame it on.
