Defend Poloniex with devil's advocate all you want. I sure did. I loved them. And again, And ... I kind of did, again. Then finally, Tristan D'Angosta's [persistent lack of] Customer Support, and cold neglect broke me. He makes well over $100 Million dollars a year. He can afford good Customer Support, right now. But he doesn't do it.
I loved the platform too and made a sweet penny there, but I'd warn anyone away from them now. How a company this successful could so completely neglect its users boggles my mind.
