cryptopia is a good exchange for me, they provide altcoins that are not available in other large exchanges. and at that time they often experienced problems about the security of their site. until now there is a very fatal problem so that the funds left there have frozen and most likely will not disappear again
Based on my experience, I can say that they are a good exchange, I never use it regularly but in the times I used it, I never face a single problem.
Only one bad thing I can still remember is that they have a huge withdrawal fee and it's not good if you regularly withdraw.
But then again, nothing is permanent, one site created and the other site is gone, and Cryptopia's journey is just over now.
So, I guess this thread has to be close also.
