Actually why i do not like banks, they have at least some advantages vs. current Crypto level that makes them more secure:
1.) When your bank gets robbed you do not care, because 100% you made no lose. When a crypto exchange or your wallet gets hacked you have to say mostly good bye to your coins.
2.) When a bank, at least in the EU, is going down, you have at least a Euro 100.000 garantee on your funds on the bank. Some banks even much more.
This said, there is aboout 0 chance you lose any money due hack, robbery, bankrupticy, fire, death, you name it.

I do not like banks, but someone has to be fair when comparing pro and contra and comparing.
