You should probably know by know that its a stupid idea. Why would they guarantee people to buy their tokens by making promise that they will buyback those token? its stupid. If you think that RLB will not make it then simply dont buy the token, its as simple as that. I personally sold most of my stash like 50% of the current price because I didnt think it will ever be this high in like a year or two but Im not complaining and feel satisfied with it
They have the buy back and burn program to use part of their casino profit to help to reduce the token total supply. It has many effects like convincing people about the solid engagement of Rollbit team for their $RLB token and emotionally investors will feel better when they see the project actually spend their money to support the token.
If you are a project team and already have a successful casino, you will not waste your casino profit, money to buy a token if you don't see good future for that token. In addition, retail investors will look at it and their belief in $RLB would be increased.
If any people are still doubtful about the program, they can look at BNB token and their buy back and burn programs. BNB is one of best altcoins in the last two years of bear market.
