Unfortunately, this is what happens when you invest your money in cryptocurrency tokens. Very often the price of the token falls and you lose your money. But don't feel bad, maybe at the next bull run the price of FUN will rise and you can make a profit. At least you enjoyed the free spins.
Gambling tokens are very unrealistic and with a few of such coins getting dumped in the market with out any chance of recovery make it not worth it to invest in such casino tokens, unless in situation where those tojens are used as utility coins in the casino and have to offers some form of incentive for their customers who use those tokens to gamble on those casinos.
We need to then be very selective and make sure to pay close attention to the development of those tokens and what their long-term road map can be before we ever choose those tokens as investment choices.
