What should I do if I seem to have been cheated by a friend to launder money?

It seems that your friend used your identity account, made a record of foreign exchange transactions, and then cashed in and normalized the money. Cover up illegal money through legal channels.

The key is whether you know the source of your friend's money. Is it the proceeds of serious criminal crimes such as underworld, terrorism and fraud?

Such friends are unreliable and can't be made.
