OP already has a bank. OP has a problem to solve and instead of trying to help OP, you decided to act like a dick and just whine about how easy you think crypto is and how everybody else should think it's just as easy as you think it is.

By the way—you don't have to store your credit card number anywhere. If you lose your card, or it gets stolen, or somebody else manages to guess it, or any other form of loss or fraud happens to your credit card, the company will keep you safe. The concern with crypto wallets is that most of them are actual scams, if you install one from the wrong place you will lose every penny as soon as you add it to the wallet. If you store your key in the wrong place, you'll lose your money, and if you don't store it in enough places, you'll lose it and lose your money, but storing it in three secure places is basically its own fucking job.

And that's not even to mention stuff like death—death is a hard problem for most crypto wallets, because it requires you to trust other human beings with your payment info, and the only wallets that can handle that are social recovery wallets, which aren't even EOAs.

You have to be a fucking idiot to think crypto is anywhere near as convenient or straightforward or safe as traditional banking and credit cards.
