That's what I was saying regarding the issue with face-2-face exchange via LocalBitcoins.
we have no choice, we have to give our documents if we want to use exchanges, see this case involving poloniex
Poloniex has dropped my withdrawal limit to $0. They are scamming. Avoid!
Ploniex did not give notice and this will happen with yobit, so do not deposit your bitcoins in any exchange before verifying your account in that exchange.
