As some of the above posters mentioned, I don't see the need for ROO token at all. Instead, the team should focus on adding more popular cryptocurrencies as alternate payment methods which would be more beneficial than focusing on an in-house token.
I also feel the same that adding more deposit options along with btc,eth and litecoin would be more beneficial for players who face some issues related to fees with other coins as deposit option on Roobet and with list of preferable coins they can choose any but at this time options are limited.But with more casinos adding some options like TRX,XRP and some other coins they might also be adding the same soon.Hope is what we can do at best.
Most places do create their own token because it is basically a way of making insane amount of money, one place that I know of made about 2 million dollars just purely on profit from creating it, and they kept making more and more profit afterwards but it was "tiny" compared to what they did (about 10-20k per month) just from the token part, do not forget that they were still making profit from the casino but it was more like dividends from it, so it was less than what they used to make plus depends on how many people gamble and usually there are less people gambling.
Roobet is 100x bigger than all those places, if they create their own roo token that would be sold on proper exchanges (doesn't have to be cex, could be defi), I am pretty sure they will make multi million dollars, maybe even 10? So that is the thing that makes them want to do it, valid for every casino.
