> I have bought a house, and they want bank records going back like a few months or maybe a year at most.

I had to juggle with this a little bit because I had sold some crypto for the down payment, but it's crypto that I had been keeping in a hardware wallet for years. As a result, I could certainly generate records showing how long I'd had it, but they'd be my own records based on the blockchain--not from any bank.

They ended up accepting transaction records from Coinbase, though even those mostly just showed some Bitcoin being received into the account and then being sold before transferred to the bank. But I guess that was enough for them.

In any case: I did ask about it and they told me it wasn't actually for KYC laws or money laundering. The reason they want a paper trail is to make sure you didn't actually just borrow the money from someone else. And that makes sense, since they're super picky about you not opening any new lines of credit while trying to close the mortgage.
