"Look, idiot, if you do not perfectly follow all of this op sec, your money could disappear at literally any moment. In which case, sucks to be you. Oh, and also those crypto exchanges where people leave their money - those also have a good chance of disappearing in the night. Best to keep it under the digital equivalent of your mattress."

I will stick with a bank which is regulated to protect my money, and heads will roll if funny business happens.
