Actually there's benefits given by the casino for those people who use their token, But I don't also think that one could give significant changes since commonly we see that lots of those casino tokens didn't get much decent volume and strong demand. Its like they are been left out in the scene and people doesn't give much attention with those things.
If people really interested to invest with casino token better if they choose the best and for sure we can see the overall stats since that mean they are more ideal choice to place their money. But again take proper precaution since we know that everything is risky together with those type of token since sometimes we cannot rely on how successful their casino is since demand and investors approach always dictate the possible future of those tokens.
That needs to be casino concern to see what they can do to increase the volume and have a strong demand to their tokens. That needs to be solved by them so they need to figures out how to gets the right answer or use the different strategy that the other casinos doesn't use. Thinking out of the box will be necessary to comes out with the good results for their casinos so their casino teams needs to create many new ideas.
The casino wants to have more investors that will invest in their tokens but the investors needs to be careful and always research before they decide. They can not just invest in the casino token without they know what is the main function and the benefits that the investors can get it later. The investors wants to make a profit so they must learn more about the project so they can decide it with rights.
I think that best use case for tokens that casinos have created is just getting attention. We have thousands casinos that offer same services, bonuses, games and so on. But those who have tokens, and give them for some activities, definitely going to stand out among competitors. People love to receive something as a gift, for free or for easy activities (but they must understand that such benefits would not have great value). I would not look on casino token from investment perspective. Wont consider to hunt bonuses or do special tasks to receive them either. But, choosing between casino that does not have tokens, and those who have and distributes, I would choose to gamble in second one.
The casino can attract attention from the gamblers and investors that playing gambling on their place. But the casino must know that it is not easily to makes the investors curious with their token if they don't have many reasons or benefits why they release their tokens. Maybe the investors will select the casino that have tokens because they can use the token to staking and maybe they can also gets share profit from the casino if that offers is exist. Well, that will needs consideration from each investors because they will have different thing to decides.
