This exchange reminds me of Bittrex when it was a small exchange. It is listings lots of great coins like Dragoncoins etc as well as doing so many tie ups by giving away BTC and millions of US$ in its weekly promotions.
It also as it Kucoins shares (KCS) which is a must buy as it gives 50% of the exchange's daily earning, and with the phenomenal growth rate of users and trading volume. It will soon be a cashcow!
Since joining, I have seen my profits go up several times.
