"The Xbrick users will be set by default to use XBC to pay all trading fees on Xbrick."
Does this mean we are required to buy Xbrick token for the payment of every fee in the exchange platform?
I don't think so. I think this is just like any other exchange wherein
transaction fees can be the platform token (XBC),
or percentage rate of your gain in Bitcoin or Ethereum.
Using XBC token as payment for tx fees will give you a discount.
But I want to know what's the difference of VIP users to ordinary users?
