This is a good question. Me, I am still in KuCoin. Because the reason is... They have lot of goods to offer. Like margin trading, and even futures. They also have a variety of available pairs that I usually trade. Like BTC, ETH, XRP etc.

As such, they support less liquid digital tokens.
Aside from that, there are no fees associated with cryptocurrency deposits and withdrawals.
Then when you still hold KCS you will get discounted trading fees.
Holding an allocation of KuCoin Shares affords you the opportunity to earn dividends.
KuCoin offers a proprietary trading platform that was built from the ground-up and it is one of the most popular cryptocurrency exchanges in the space.
