It's interesting to note that, at least IME, that the thing that used to be a feature on bank accounts ("hey! we suspected some fraud on your account, so we're calling you about it") is now used as a trigger to investigate the customer, particularly if they're a crypto user.
I now treat interactions with my banks the same way you're supposed to treat interactions with law enforcement: saying as little as possible, don't answer what you're not asked, and with the knowledge that EVERYTHING you say is going to be used against you to close your account.
