I can confirm Cryptopia is at worst a scam and at most extremely incompetent and negligent to the point of being illegal. Its fine until you have a problem, and then suddenly it is seriously not fine. This may be days or months down the track, but eventually you will be hit with a problem, and when you are, god help you if you ever want to see your money again.
Personally, I had used Cryptopia for months with no problem. I was getting more confident with crypto and trading, and I saw an opportunity to make some small gain by finding a difference in the spread of an altcoin compared to another exchange. I transferred some bitcoin to the other exchange, changed to the altcoin, and transfered back to cryptopia. However this deposit did not arrive. I know the blockchain can take a while to process so i wasnt too worried, however as the hours started to drag on I was starting to feel uneasy. It was a very high risk altcoin with wild fluctuations, hence the potential to make money on the difference in exchanges, however as I saw the blockchain start to gather confirmations and still no sign of it in cryptopia I started reading these forums and got a little panicked, I went to their support page and saw no contact details, no phone number, no email, only a ticket system with a wait time of 35 days. Wait... 35 Days?!? That must be a typo??? On a multi-million dollar financial service provider where daily fluctuations mean millions of dollars come and go and there is a 35 day wait to look at a problem? By now I was in full panic mode, I tried to withdraw all my coins from Cryptopia, and got the dreaded processing error.
All I could do as the hours, now days, ticked by, is watch my portfolio plummet. It was a high risk trade and i made a nice penny, but now I am losing about $100 an hour for every hour I cant withdraw. After 3 days, and now hundreds of confirmations on the blockchain, my coins were finally processed by cryptopia. After reading these forums, I consider myself lucky to only have only waited 3 days and lost $7000. Support never replied.
Now you my say, that is not a scam, thats just network errors, however, when dealing with millions of dollars, no support, Cryptopias own coin explorer said no problems with that coin, the blockchain has processed it, and Cryptopias own terms and conditions state they are not responsible for network problems outside of their control, however this was Cryptopias NETWORK and under their COMPLETE CONTROL. They were legally responsible to cease all withdraws / deposits if there was a known problem, would you feel safe depositing in their exchange again?
I will never use this service again and I seriously urge anyone who values their crypto portfolio to stay as far away as possible.
