poloniex is not going to scam in the way people are expecting them too, that would be way too obvious.
they are already making shady moves that we can say they are already scamming people!
haven't you seen the recent shenanigans with the altcoin dumps! they dumped on their users while none of them could make any trades
and each time they simply say the number of users grown fast and we were under DDOS so we couldn't handle it. and people forgive them! and again get dumped on.
