The latest hacked case of cryptopia can be considered as the main thing to make that shitty exchange site will declare its bankrupt. Cryptopia's volume has been drained by the hackers. it will be so difficult to recover.
Other exchanges who have been hacked didn't drought after their hacking incidents. But this is going to be hard for cryptopia, a lot of traders will come out of them and going to stop using them. I don't think it will be so difficult for them to recover, there will be traders who will still be confident of using them but many will loss their trust.
