There is no reason to trade on these dex though, you are going to end up paying extra on all those fees. Deposit to Rollbit directly using the lowest fee deposit option then purchase RLB onsite. Most RLB trading volume is also onsite plus you could always store those RLB in Rollbit or pretty much put them in the liquidity pool if you have enough of it
What will happen with $RLB price if it will be listed on Tier 1 exchanges like Binance, Kraken, OKX, Coinbase?
I don't know that Tier 1 exchanges have their rules against tokens initiated by online gambling sites and I believe that Rollbit does not have issue to list the token on big exchanges. It is my hope for future like two more years as the team must build up good usability for the token before spending listing cost that is not cheap. They must do it with good benefit from listing effects which would be bigger than the listing cost they have to pay.
