I have no idea what proof You expect. Even if I give You purchase invoice or bill, You are not sure that I replace cbr for silver coin after POS, soo the reason why I did Proof Of Developer.
Proof of Developer doesn't mean a damn thing. It's just a worthless service that scammers use.
Proof of Dirtbag is what it should be called.
There are many worthless ICO's that cost people btc that received a worthless POD. So cut the crap. POD means nothing and this is still a scam.
