Banks don't close a customer account like that , where have you see this ? "Suspicious" is not enough to decide to close the account of anyone LOL....
There are banking laws and customers rights. It's not the cow boy period where banks talk and you just shut up and obey
to be honest they can close accounts pretty easily and I'm sure that there were several occasions in other countries where banks decided to close people accounts just because they traded bitcoins or something. That's why I don't trust banks at all and try to use their services as less as possible. In the end governments will be trying to ban bitcoins for sure and we will need to do everything to conquer them.
Guys who would not say that we are all now dependent on the banking system and why some have problems with the bank, while others do not. All the problems in most cases, customers themselves provoke. But there are positive aspects of the existence of banks to date. I use all of their services for a long time.
