The tokens that do well ...are the tokens with utility ..and having only 2 or 3 casinos accepting FUN as a deposit option ..does not really help it's cause. It is a bonus that it is still listed, but it needs a lot of trading volume to stay on there. 

Also, we know all Alt coins take a knock when the Bitcoin price goes down... so it does not come as a huge surprise that the FUN token will also take a knock ...seeing that the Bitcoin price has dropped this much.
