Though, It seems to me that we could conclude thanks to the reports of some gamblers who have tried to withdraw their fund tokens from the casino, that Freebitcoin itself seems to be experimenting a lack of liquidity in their own native token, that is why they could be having such insane withdrawal times for people to get their FUN tokens.
There are even a couple of users who claim never getting their tokens after the system of the casinos discounted their balance as if the withdrawal as successful, all of it because the casino address did not have enough Tokens to fully process those withdrawals.
It seems to me it is more reasonable for users of Freebitcoin to keep with balances in Bitcoin and not swap it to FUN or try to capitalize from the token, as it could be translated into financial losses.
One can hope the people behind this casino does not run out of Bitcoin either, in the same manner they seem to be having problems with FUN.
