UK banks are scum and are shutting down all accounts used for Bitcoin activity. Unfortunately, I am going to be taking my marketing agency abroad if I can.
i have seen 2nd hand 20 businesses that are bitcoin related, but tell their bank business account manager that they are "marketing" or "advertisers" or anything else but bitcoins. but when it is found out later that the banks have been lied to... its the lie that shuts them down.. not bitcoin.
my bank manager knows about my bitcoin business, and so far 2 years on.. no issues.
simply put if you lie to a bank thats a big red flag not to trust your ethics and morals. thus "suspicious activity" flag is highlighted. especially if your doing transactions over £800 a day to random people.
