Be careful! You are getting yourself into a big trouble. Many people got handcuffed because they withdrew a huge amount of money which seemed to be suspicious. And then they happened to be scammers and hackers. I know you have not done anything wrong, but bankers will think your money is suspicious.
That's pretty much a pointless warning. If you are a hacker or a scammer and use a bank to store illicit capital, you should be getting your butt whooped by the authorities, and there is nothing that people can say to counter that.
Banks everywhere in the world have been upping their internal policies regarding potentially illicit capital, and that hasn't changed. You only have to worry in case there is no way for you to prove the legitimate origin of the capital.
In that case, any financial institution should be avoided. However, if you know their trigger points, and thus maintain to use that whatever bank with capital below these trigger levels, there won't be much of a problem. I have learned that too.
