Once the exchange exists there will be greater volume since XLR will be a trading pair for many coins. Think of the other exchanges out there that have an "exchange owned coin" just with the difference that Solaris already existed and has Masternodes on top of it.
Txbit.io exchange will play an important role in potential growths of Solaris in rest months of 2018.
Big boosting force for Solaris project when Txbit.io exchange officially launched and open for trading.
We shall see ( if txbit.io makes it in 2018, I'm not so sure ).
All I see is no real point for the value of the coin to go up, and our steadily declining market value and volume.
Other more significant coins/projects have had trading pairs for years, and they're still very very behind BTC pairs volumes and price of course.
I feel like we are in forever at under 5$/XLR.
If you insist, I'd like to hear your prediction for the price of XLR once txbit is up.
