I agree Kucoin is better, but Cryptopia has also some really good coins there
Kukoin is a good exhange. But still to small with small daily volume. DeepOnion must hit to Binance without dobts! Binance is # 1 world exhange. Also Okex, Huobi would be great to see.
I haven't tried kucoin yet. Still waiting for the airdrop to finish then probably i'll try trading there.
and their technologies looks good.
Kucoin exchange will grow definitely
