Until the bank catches on. First they will watch all activity regarding your account. Then they will notify the Federal Reserve who will notify the other banks. That's when the Treasury Department starts issuing subpoenas. Then a federal attorney will take it before a federal grand jury who will indict you. Then you will be arrested. Your family can either make bail or leave you sitting there in jail until trial. Now, if you cannot afford an attorney who is licensed to appear in federal court, one will be appointed to you. With regular jail sentences, you have to serve a minimum of 30% in most cases. That is not the case with a federal sentence. They are balls to the wall.
So....is it really worth it? Cause I don't think so.
