Banks are shutting us down

So one bank account that I use (because their transfers are very speedy) got restricted earlier this year because I was using it to deposit some money to Kraken and the account got restricted after using it for crypto lol.

It got opened shortly after I gave some proof and explained I understand the risks involved of dealing with crypto blah blah blah but today I deposited some more from monzo to the exchange and now my account is being closed for an undisclosed reason (I wonder why lol).

What’s with banks trying to control how we use our money? People can blow their money on alcohol and gambling but I can’t choose my investments after I’ve researched?
