All the gold I have bought probably over 100m overall, I have never been banned for a real world trade. It's always good to have a account you can stock money on to in so that your other accounts, what are at risk wont lose all that money. Whenever I buy gold i will trade it from 1 account to another account and then to another account, this seems to work for me but maybe selling gold has a much higher risk than buying I dunno.
