It seems to me that listing on 3 exchanges is quite enough. You can always buy or sell GFR coins.
The liquidity of the coin should be increased, added to new exchanges, this is a good way.
Adding in more exchange will not help with project liquidity,. What i it needs is a real use case for their coins, launching their casino platform will help in creating an economy behind the coin. Until then this will be just a purely speculative trading coin without real use case.
