Sounds like we have haters here or one of the casino's competitor.
Sounds funny but remember in the first place dogecoin and bitcoin are far different which is Bitcoin until now exist but I dont know Dogecoin still there is investors. Freebitcoin has been here for over decades and I dont think they will fall, there are too many casinos out there that already collapse but this casino will still lure gamblers through their faucet and free-given away just like the free spin mentioned above.
Seems like a new troll that has criticism on everything they do... Freebitco.in is the oldest faucet around and keeps on innovating (WOF spins, premium membership with FUN tokens, new casino sites,...) so the chances they fall are near the zero.
