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.
