Yes, exactly that. And that's why it's interesting. You play, you have fun, and you opt for the dividend whenever you want. And the more you repeat this, the better the return will be over time, although the dividends will decrease, the tendency is for more users to bet too.
The problem is, that usually gamblers claim their daily dividends and referral commissions every day to gamble. This is why they cannot manage to make big amounts from the dividends or referral commission funds. I don't know if GLX can be used to play their games. If it is possible, people are likely to gamble away their GLX tokens as well. If the casino does not allow to gamble the native tokens, that will be good for the players. I had some native tokens in different casinos which earned me dividends, I wanted to increase that by playing games but ended up losing them all.
I did the same on another casino but luckily for me it turned out ok and I didn't loose any tokens but I would never gamble again with tokens that give out a dividend as I love passive income While people might gamble away with the dividends they get, they will also earn more tokens which will result in even more dividend later on.
