Where else are you going to store your money mate I suggest going double ways or dividing according to your risk management Crypto still require fiat onramps and thats why banks are required and basically crypto is not mainstream yet or maybe buy some gold if you are curious Wealth can be stored in various ways Make your decision
diversification is always the key, always try to store money in various assets then it will be safe.
even though I always think bank as somewhat secure and what I mean with these kind of banks are those banks that are massive. which simply too big to fail.
even if they somehow collapsed there always ways for them to go back up again.
but then again diversification is honestly easy thing to do and it saves us from the possibility of losing our investments and money.
