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.
They had shut down Freedoge.co.in for 2 reasons.
We closed Doge down because it was never profitable and we were encountering more and more problems with the Doge core software being unreliable. The code hasn't been maintained for many years there is no hope that will ever get sorted out.
However, the primary reason for closing Freedoge.co.in is that "
there wasn't enough gambling volume". They were unable to generate profit for this. Frebitco.in will be shut down as well if the betting activity of the users decreases significantly. Because they don't have any other source to generate revenue and run everything smoothly.
