Cryptopia was beaten up because their systems couldn't cope with the volume and support requests were astronomical. It is only logical and understandable that users became upset.
As a mod I tried to do what I could during that time. The rest of the time I largely ignore that thread. Usually Lafu is on there on his own trying to do his best with limited English. Every exchange gets hammered on here. Exchange users don't read, don't research and have opinions about things they know little about. They hit the nuclear button when their funds are stuck and disappear once it is resolved. They gravitate to here to voice their opinions on here because abusive behaviour is largely unmoderated. I prefer spending months unravelling complex scams where people have actually lost funds and preventing others from losing their funds.
All those crappy exchanges with support issues made the choice to neglect their customers. They could have stopped new user registrations or deposits or otherwise slowed down their growth to allow themselves to catch up but they didn't. Cashing in on the bubble was too important. It's quite disingenuous of you to blame the customers when Cryptopia's policy has been - and still is as far as I can see - "send us the money but if you want it back be prepared to wait three months for your ticket to get resolved".
I would suggest that you walk away before you dig the hole too deep. That whole Cryptopia nonsense is just gonna earn you more red trust for shilling this shitty-borderline-scammy exchange. Trust is not moderated and mdayonliner is not in DT so there is nothing you can do.
