And why the very small amount of 9 thousand dollar from an already indentified customer would give any red flags regarding illegal activity? BIG LOL.
To be honest, $9000 is a pretty shady number in the world of AML/KYC. Sad, but true.
It is not, it is not aimed at street drug dealers, it is aimed at political corruption, organized crime etc but it does not matter. Just to make sense of it all. Just ask youself if your bank, which must comply to KYC, where you surely have more money and transactions has ever frozen your account or required invasive information about you under a treat. Ask your friends, ask your relatives, ask anyone. They all will say no! It does not happen 'cause it is
not required and if you are in good stand with your bank it is even illegal to freeze an account without a judicial order.
The first bank ever to behave like Bitstamp will have its reputation ruined and will be in legal trouble.
