More and more banks keep asking for your entire crypto transaction history when you want to convert it to fiat currency.
This is to make sure that all taxes are paid, and that the person who converts crypto to fiat did not get it from criminal activities.
I will advise that those that are into bitcoin should not connect their account to cryptocurrency in bank, they should treat each separately and this is for their own benefits, I don't think it's ideal to connect your crypto transactions to your bank, instead make use of the p2p on exchanges and receive your payment with the bank interference, because of their regulations that may cause you lots of disappointments.
