As I am aware, but correct me if I am wrong, none of the gambling tokens ever made anything spectacular, while some meme coins made some crazy returns. Maybe Elon is the one responsible for that, he started talking about Doge and (one of the biggest surprises in crypto in my opinion) Doge ATH was $0.74... Now we have a lot of meme coins around and it seems that many people are trying to make a fortune with them.
I think it is not fair to compare the meme tokens with the gambling tokens. The meme tokens have no use case and they rise or pump based on the hype and they are usually very short-lived.
On the other hand, the tokens with use cases like gambling tokens have a proper project / use case and they tend to remain alive for as long as the platform is around. The success of these tokens depends upon how good is the gambling site and what is the use case of the token.
I also think that gambling tokens are not so popular even among gamblers, some people like them, and some don't... anyway, those who like to gamble in dividend-based casinos will earn them just by playing, but it would be interesting to know how many non-gamblers invest in casino tokens, and if there are any at all.
Well, there will be a time when gambling tokens will get hype. Some tokens may not remain in trend always and it is only a few times when we see a rally in these coins and gambling tokens fall in this category. I feel that the Fun token will show some good returns in the peak of the bull market and alt season, although the current prices of the FUN token are very close to their all-time low.
