Kucoin is a very large cryptocurrency exchange and of course there are many better events with a variety of coins.
I also believe that trading cryptocurrencies on Kucoin is really a wise and more reliable choice.
I chose a good coin for cryptocurrency trading on Kucoin and that coin is BNB because with BNB we can see that BNB is a perfect coin and worth trading.
I personally prefer in binance than Kucoin, although kucoin is also big exchange.
But I also agree with you , BNB is good coin for trading.
I have several times got profit from BNB but not much.
For large profit, I usually choose new coin listed in binance and sometimes in Kucoin.
My best coins for trading are BNB, ETH , and BTC.
