I just checked the Whitepaper and i saw the costs for trading fees (0.05%) this is very low costs your exchange need a good marketing plan..
Ya I definitly they should be including it in their marketing materials I mean getting these kind of fees is great and should easily draw traders into the company
The best option probably would be to remove all commissions to those who actively trade in the first time. This would give the exchange an increase in liquidity which would immediately lead to the fact that they paid attention to it and those who do not trade so often.
And to take your income the project will be simply due to the listing. The best option in such market i think.
