KickToken (KICK) and KEX have different purposes. KEX will be credited to traders in the form of reward for trading volumes, as well as be used to pay for some services and reducing trading commissions. But the main token circulating in the exchange will be KickToken (KICK), because it can be used as a payment for most of the services.
In the future, KEX token, as well as KickToken will be swapped to the coin of Kick Ecosystem own blockchain. The bonus at the time of the transfer to a new blockchain will be up to 100%, depending on the volume ratio of the owner.
