Revolut (in Sweden at least) has now made it impossible to withdraw BTC to a hardware wallet because of "security". Had to try various methods to get the BTC out and eventually found that using OKX wallet works. From there, I could then send the BTC to my hardware wallet.

During the past year, Revolut has increased the controls and restrictions for withdrawing BTC (it seems they have been forced to do so), and today I wondered whether it soon will be impossible to withdraw at all. Will be careful not to store too much on there.
