Poloniex is shit platform.  my account had been locked since August 2017  for no reason.(It can only Login and Login out.  cant see my balance ,cant trade .)   and my account have many  coins like VTC, EMC2 .....  And  i created many  support , but only bot reply . No a  custom service  to handle my problem...

Fuck the poloniex.  So it is very dangerous to trade at it.  I suggest all you guys will not  trade at the shit platform..
