If anyone still wants to buy. I recommend Bit-Z even though they require KYC for withdrawal. Cryptopia is having some trouble with their withdrawal process and it took me more than 2 days to be able to withdraw the fund out. They are extremely understaffed for support right now when I talked with their admin.
If you only want to trade on the same platform without withdrawing, Cryptopia might be fine though.
I have used cryptopia for at least a year and never really had a problem with them, maybe twice they had maintenance so the wallet was offline but 99% of the time the withdrawals worked in under 5 minutes. They might be getting slower as they have more traffic these days but I'm sure they will add more staff if the traffic is consistently high enough.
It might be right back then but in my case, it took them 1 day to reply the ticket, and another 1 day to manually push the transaction. I talked with their community admin on Discord and they are having an influx of newcomer due to recent promotion and being understaffed. That's all I can say, pick your own choice though. In my case, I got unlucky with an error in their withdrawal process, if you are lucky, nothing to worry about. But my main point is still that they are lack of support at the current time and won't be fast if you need any help.
