First of all, do not compare FUN tokens with ETH. Both have totally different use cases and we cannot compare the development in both the coins. As long as freebitco is growing, the fun token price will likely move up. They just need to find more use cases in their gambling site and that's all. I would say that fun token can be accumulated in the current bear market and will give good returns in the bull market.
One suggestion is why not start an hourly faucet for fun tokens on freebitco? Just like they have a faucet for bitcoin, another faucet for FUN token will make a big hype.
FUN token is having a good usecase and that is to serve as a reward in the freebitco.in website as well as being used at other casnios like dplay.
On freebitco.in we already have a faucet for bitcoin and so another faucet for FUN tokens wouldn't make much sense.
Also, creating another website just to have a faucet for FUN token also wouldn't make much sense.
All in all there has to be a whole new website with games and stuff, basically a casino where they can include a faucet for FUN.
