I have been watching the Au coin since 2014. Long ago I had 600 coins and sold them cheap. After
my stupid mistake I always buy this coin and do not regret. Au  always bring me profit without any gold. But for all the time, for the first time I see such volumes on Coinexchange. Given the low mining of less than 2 coins per day and the fact that almost all the coins are in the hands of the same people who never sell their coins cheaply, the appearance on the  exchange of so many cheap sellers causes mistrust.
   Such activity of new people here also causes distrust. . Why has cryptopia frozen trade since summer itself? And then immediately attack 51%? And the eternal expectations of conclusions for 3 days or confirmation of input for days? It's good that I stopped trusting this exchange at the beginning of last year after some losses with other coins also !
