It might not be easy to sell Freebitco. Rollin.io and few other very popular crypto casinos wanted to sell their website but they failed to find an actual client. To my mind, if Freebitco was a website similar to Rollbit, Duelbits and etc, they would easily merge with other company or sell the website to famous casino like Stake. Freebitco is a faucet-based business, which doesn't work these days, so I don't know who really wants to buy it because if someone plans to run a faucet business, they'll fail but if someone wants to run other business, then domain name isn't the best choice because it says free bitcoins.
Well, the faucet on freebitcoin has been a secondary option for a long time. In fact, in the last few years, freebitcoin could be called a gambling site because of the emphasis on spins, betting, lotteries, and the hi/lo game.
And it seems to me that the reason why they may have a hard time finding a buyer is that they don't even have a license, unlike many other crypto-gambling platforms.
