Yes, the gambling tokens are worth investing but all of them are of cheap prices because of the bitcoin bear market. If we accumulate these tokens now, they can give us much more returns when the crypto bull market returns. I would say that invest an equal amount of money in BFG, OWL, TFS and FUN tokens. Currently, these gambling tokens are in high demand as their gambling platform is gaining popularity.
If someone is targeting these gambling or casino tokens, the bear market is the best time to buy them because they're at the cheapest during this season.
They are designed for long term if the casino is very much popular and you can see the stability that it has got based on its situation and operation.
It's good to expand some budget on these tokens if you're decided and you want to have that part of diversification from these type of tokens. IMHO, I'd like to have a few of them but to enjoy the perks that it gives to its holders.
