The question i think has a pretty obvious answer, not being a total biased here but in just 2 years kucoin have achieved so much than any other exchanges. And i feel like there is not competition going on with kucoin exchange and the other exchanges because kucoin is showing a lot more potential and stability.
So yeah, the answer in this question would be "YES": https://www.reddit.com/r/CryptoMarkets/comments/de50g2/is_kucoin_exchange_safe_to_use/
