I think that it is really difficult to predict the trends in the development of gambling now.
It is not that difficult if anyone is active on X.com or Reddit as most trends emerge from these two platforms
Imho twitter (no i am not calling it x), is a bubble that's riddled with trolls and bots now. It's mostly an echo chamber and poorly reflects on any large trends, other then their own they choose to promote.
Also when it comes to your original question, why it would make sense to make gambling platform for this, when you can literally just buy those tokens that you predicted to be trending and get winnings directly without casinos getting a cut from it?
But changes of winning in both cases are slim to none. Even if you could predict the next trend before it starts, you would need to choose the right tokens that are participating in it. And that's not an easy task. There's a reason why some people are calling crypto trading as gambling.
I also partly treat cryptocurrencies as a game of chance. This is probably fair simply because the history of cryptocurrencies itself is replete with cases of enrichment and, of course, ruin of many people. And these were in many cases completely random events or combinations of events. In this sense, it would be quite correct to compare all these games with cryptocurrencies, as well as many trading operations with them on crypto exchanges, and classic gambling.
