In my opinion, Gambling tokens and related coins cannot only be about attention and hype, otherwise, there would not be much different between a casino token and a memecoin like Shiba Inu and Dogecoin. Since we are talking about an asset which is directly tethered to the performance and perks a casino can offer to the holder of such token, then we could say there is an actual use case for those tokens (It would be matter for the market to decide which is the right price for those interested on enjoying those perks).
I would have personally invested in casino tokens if I had the chance and budget to do so around a year ago, and I don't even myself to be a big gambler, and still... It is all about especulation and the desires for profits, as always when we talk about trading .
As the market stands today, people are more focused in Bitcoin and memecoins than casino tokens.
