Kucoin is a Chinese cryptocurrency exchange similar to Binance that pays out 90% of daily exchange fees to their token-holders. For an exchange to share that much revenue is a very clever way to incentivize token-holders. How it is done is even more clever... each day they pay out dividends in the forms of other tokens. So just by holding Kucoin (KCS) tokens you will be paid daily in Bitcoin, Ethereum, Neo, Litecoin, as well as any other token they list on their exchange.
This will allow many people to start accruing digital currency tokens they normally lack the time or money to invest in. All in one interface they can start collecting multiple tokens in their Kucoin wallets.
