I think it's a site that still operates thanks to its past fame.
This is most likely the case, as many crypto enthusiasts encountered this website when they first entered the crypto industry 5-10 years ago. This explains why some users still remain loyal to Freebitcoin and continue to use their site despite constant issues and increased risks.
Provably it is since we still see people complaining towards their withdrawals.
And its somehow not surprising to see those things knowing how big their platform. So for sure that there are still people will try to take a risk and gamble hoping that they can get their withdrawals even if there's a delay will happen.
If they just choose to take care their community there's a chance that their casino would still profitable.
