I agree Kucoin is better, but Cryptopia has also some really good coins there

Kucoin surprisingly is my second favorite exchange after Binance, even though Cryptopia is working on the deposit withdrawal problem,
Kucoin is still better option to me, but you are right that there are some good coins that aren't listed somewhere else.
I like the security offered by Kucoin, it is also fast, and the graphics are better, for me it is the best, very superior to cryptopia.
