When can we see PDATA on Binance ?
They did not even finished their pre-ico, how can they know ?

Binance is too far away for someone to know exactly when they will be listed. They will probably list the coin on smaller exchanged like kucoin,etherdelta.
They will probably start listing on major exchanges in aproximately 30 days after the token sale is over, that information whatsoever is confidential so we just have to wait and see
