The communication is confusing about Cryptopia.  They say it's fixed, but it isn't.  I don't know why it's like that either.  I did see something about a pool being hacked and a large amount of stolen coin being sent to Cryptopia.  Maybe they froze the wallet to try to somehow recover the stolen coins but that is just speculation on my part.  They should say so if they are trying to help out with something like that.  Maybe I just have wishful thinking but trying to think positively rather than just "they suck."
