That's all marketing. The usual way of marketing is through bounties but once the token has already gained traction, popularity, and momentum. They don't need it anymore and that's why they're going to focus on the use case and development of it which goes under the casino itself and why they've made the token. And the fact that they did a token is for their improvement and other offers to be good and that's why they've done that. Also, they can use any other marketing aside from those bounties and I do typically see most ads pop on search engines.
There are many ways that casinos will use to attract gamblers so that they can get more members who will register on their site. Giving bonuses in the form of tokens is one of the ways that casinos may often use. Before the casino gives bonus tokens, the casino needs to consider how members can use the tokens to their advantage. If they can give this to their members, there's a good chance that more people will join the casino for bonus tokens that they can use for other benefits.
It's like a domino effect that they've seen this success of making tokens from the other casinos. And it's all really about crowdfunding to help the site upgrade and become better.
I salute those casinos despite their popularity, they're not dwelling and diving into this idea of having their own tokens because they can sustain their operations just how it used to be.
Yes, the casinos seem to see the potential to launch their tokens to provide other benefits to their members. But it must be accompanied by other efforts to make their tokens successful. For casinos that already have popularity, it is unlikely that they will do that because they will think of other things that can make their casino always get a good reputation. Popular casinos don't just want to keep up with the current trends because it doesn't necessarily work for their casinos. They should focus on what they are already doing and keep trying to improve it.
