I think the same thing will happen to this site in the near future as to their previous site:
https://freedoge.co.in/If I am not mistaken, they decided to shut down freedogecoin due to massive cheating and abuse by some users. In other words, it was not feasible for them to spend resources on that site.
As for the freebitcoin website, even if it shuts down, it will clearly not be the same as when freedogecoin shut down.
You’re right, however there’s a basis too on why he fear that it will happened the same since freebitco.in also give rewards in the form of faucet and investment of FUN token.
I doubt their casino is generating profit compared before due to competition while the passive income from players is continuous.
Their silence and delay of improvement might be a signal that they are struggling already to maintain the profit sharing to players.
