yes, kucoin is a new and highly develop exchange, it may be the next binance, so better to listed on kucoin as the difficulties is not so big
Kucoin is a relatively new exchange with little amount of listing so far. So the competition for getting in isn't that tough at the moment. That means It's the best time to to start working on a way to get a listing on the exchange.
The AE team is doing fine with developments at the moment but It'll be good If the team also focuses on marketing so everything will be balanced. More exchange listing like kucoin will bring about the much needed Liquidity
