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 bought BTC and sent them on cryptopia today. I exchanges them for BTX and send it back to the qt wallet. It took less than an hour (the whole process) and i already have BTX in my wallet ready for the airdrop. So I have positive experience with cryptopia.
And don't forget what bit-z requires documents verification and 2FA - so it can take 2 days. But after that btx transaction less than 30 sec.
