I got a lot of bank accounts a while ago, because I know how difficult it can be dealing with banks when using crypto. Fortunately, I didn't have any problems, so I started closing a lot of them. The idea was to spread funds across them so if any one bank cut me off, I could still pay bills and live until it is resolved.
Banks are criminal organizations funded by the government. Once you give a bank money, it becomes their money, not yours and you are blessed if you are allowed to spend it when you choose.
