What would be the main reason of trying to withdraw the FUN tokens? If you have some left, I would just cash them out even the price you get per FUN tokens is a couple of satoshis.
Some people withdraw their FUN tokens probably because they can sell the tokens at higher price outside freebitco.
Currently, you can exchange each FUN token for 0.0043 USDT at binance while the sell price on freebitco is 4 sat which is worth around $0.0038.
If you have a lot of FUN tokens that might make sense but I don't use Binance anymore and the withdrawal fee is also quite large.
Never say never, if a new management would jump in and can clear all the air and they can prove themself once again, then I would use freebitco.in again
In my opinion, with this same business model, I highly doubt that even if someone bought the site, things would improve. A few years ago, the price of Bitcoin was very low, so it made perfect sense to have a faucet, but nowadays it no longer makes sense. Also, this casino token thing, in my opinion, is a bad move, because the value of the token hardly increases much each year. From what I have seen, the value of these casino tokens remains stagnant. The site needs to make a lot of changes to be able to compete with other good casinos.
But it is still a popular site with a lot of active users and people still wager high amounts so that can attract new investors. A faucet nowadays doesn't make sense anymore but if you were active in the very beginning, you could have made good money just by doing the free rolls.
