If you lose your keys you haven't understood enough what self custody is. I mean, you are ready to own a great amount of bitcoin the moment you are really confident with that technology...... so: we all need to study and use again our beautiful human brains (otherwise one day AI will fuck all of us)

If you need fiat money just go on, for example, binance..... it will take few minutes. Get an account kyc ready to use just in case. I use Revolut and I get fiat on my account in few seconds and it happens when I have to pay something and I don't have enough fiat stinky money:)

But one question: and if your bank account is not working for any reason.....? What you do? And if for some reason government wants information about you and in the meantime you can't use your bank account? And il tomorrow you country get a bomb and banks close for a while......?

I feel good:))
