HI!

A co-worker, who is a news trader, has asked me, if I would give him my passport copy and bank account info, as he needs different trade accounts (or something) - he said, that he will give me 30% of his profits. As I don't know anything about online trading etc. I wish to ask you, if he is doing anything illegal? Of course I ain't giving him anything, but I'm just interested about legality of his trading
