Gambling platform tokens have not flourish well so far. Betfury is relatively old project, but little progress has been made on it. However, developers efforts are ongoing. They plan to list on better exchanges in future. Owl Games is one another gambling platform which is in a much better position. They are constantly developing. Even it is a new project, there is a high possibility of getting success.
The value of the token/coin depends on its usage. Not only the casino platform but the developer should increase the demand for tokens. And along with that should be listed in good exchange. I think currently casino players are increasing but coin prices are not changing accordingly.
Because we are in a bear market, if you checked the price, on Owl token you are more than 400% profit if you've invested 10 months ago on BFG the price is also performing good in the market and even if the price is moving you can stake these coins and earn profit from staking, casino based token its one of the type of coins worth investing, they have the platform they have the community and they have dedicated developers all the things that you're looking for on a coin.
