It is not late to invest in the token because we know bull market has yet come with us.
They are trying to add more utilities to it with advancement in the system but still we can't say in the bull run it will go up because it will depend on how people see it and benefits of holding it to them as they are for usage in casino not outside so scope is limited but still great chances to make profits out of it.Well I sold most of mine at decent amount though so Im pretty happy with it. It coul have been atleast 8 fold of what I got if only I had waited abit longer but hey its free money after all so no complaint here. Pretty sure that there are alot of folks out there that still keep their stash from the Rollbots but Im going to be honest that I was abit skeptical with RLB back then so yeah I sold most of mine 
That's understandable. In my case I chose not to be in rush (since it's an airdropped coin). Though I won't deny that it is tempting especially Rollbit made it easy for having their own exchange to buy/sell. But seeing how much the price increased from months ago, I can say I made the right decision.
