If in my opinion throw away Kucoin shares and buy Binance coin, because Binance is better than Kucoin,
especially in terms of future security, obviously Binance is good at that, 7% for KCS is a big amount, be aware of that and you will not regret it
I agree to you that BNB has more development upcoming and chance to survive the ups and downs of market than KCS. I am also more confident to trade in binance because CZ will not let its investors to stay away from Binance. BNB has more utility and its development is quiet crazy. I have invested in BNB since the start of this year because it is my long term hold as well as ETH and BTC. However, it is up to OP of which he think is good to buy and probably will paid of soon as the market have bull runs.
With the news that KuCoin was hacked, KCS's popularity declined, so it's not a good decision to invest in KCS right now. I agree that BNB is
much more profitable than KCS, especially since BNB has a team of developers who are quite active in promoting. So the demand for BNB
continues to increase, so the price of BNB also continues to rise. I've also bought BNB to hold, and hope BNB can pump the price later this year.
