Be careful,he's probably trying to launder money or to hack your account
I wouldn't trust this guy
Yep. If he's moving this money under your identity (As every seller nowadays on LBC needs to have done KYC). I'd highly recommend to NOT do this, not only are you potentially laundering money, but by letting him using your identity, you're opening yourself up in a way that you really don't want.
I. He can further commit identity fraud, misusing your data, whatsever is on your LBC.
II. You can be assessed for taxation over the amount that is traded.
III. You can be seen as a complicit in laundering money, funding criminal organisations, et al.
He has an ID himself, why doesn't he use his own?
