I have suggested make those who more tokens have greater bet boosts in sports betting.
Is something like that possible? I would actually be happier if holders of casino coins in a certain amount could also determine the VIP level of their casino account and receive some additional bonuses that are not offered to regular customers. I really don’t know if your suggestion can be implemented by the casino, but it is indeed interesting.
For casinos that have coins, they should indeed think about offering better benefits to their coin holders. Perhaps the lack of attractive offers is what makes the development of casino coins uninteresting at the moment.
Why cant it be impossible? Long time ago when I used sportsbet.io for betting, they gave bet boosts. I dont remember if they were given for specific sport, or they were bonuses I could active, but I remember bet boost could increase odds for 0.1-0.2. I wasnt a VIP there.
Just make it like this: for each thousands casino-tokens you hold at casino balance, you get 0.01 bet boost. The more you have, the bigger is the boost, but there must be limits also, so that huge holder wont turn 1.01 into 3.00

At least with that, people would be interested in buying those tokens.
