We live of generation of refund, in crypto main thing Are refund what i did learn about.
They have to refund
No they do not.
There have been dozens (hundreds?) of times when exchanges got hacked and people lost their coins and got nothing back.
There are countless times when people got their user info hacked and lost their coins and got nothing back.
There are dozens (hundreds?) of times when exchanges just closed their doors and took everyone's coins and they got nothing back.
And so on. Get a hardware wallet, learn how to use it and keep your coins in your control.
Anything else is just asking to loose them.
