For listing by vote like this I think which project/coin has bigger community will be the winner
. And it's fair if you don't wanna pay BTC for Kucoin to be listed
.
Airdrop for voting is a good way to attracted people to vote for any project/coin to be listed on kucoin but at the moment I think almost new projects and coins often pay attention to big exchange like Binance cause it's the best place to be listed at the moment
