I hear from some people that when selling a large amount of Bitcoin and having that money hit their UK bank account, the bank has froze their money or notified them they will close their account.
Other people say they had no issues and no one has said anything.
Have you have any problems and more importantly who gave you the best rates and was the least hassle to deal with.
It depends of course. I've noticed that most of the people saying that their account was frozen upon withdrawing didn't state where or what is the source of that certain amount(So as the bank's "Security Features" they are going to investigate your account). Unlike those who've stated or has documents where are the funds came from has no issues.
