Since from the beginning I entered crypto space, and started opening accounts on different exchange, my coins are all still in there, and nevere had been decreased, so I am perfectly comfortable leaving them. They would surely send me an email if theres a problem, also I have out security measures, 2fa and just to be sure my coins are all safe from being hacked. Never had the experienced on being snatched by some weird exchange.
You are just lucky but not entirely safe.2FA doesn't save you if exchange's got hacked.It only saves while others try to bruteforce your password or something like that.
OP is pointing about some exchange who suddenly disappear or shuts down their exchange in approach to bull run.
The issue raising by OP is not about hacking or scamming, but the security of our funds when we store it on exchanges.
The user who I replied thinking that he can save his asset even if the exchange got hacked if he has 2FA security activated but its not going to save your assets,it only saves you account.
