The Crypto Gambling Foundation has only 7 members (bustabit, bustadice, bitdice, stake, primedice, betking, and nitrogensports)
That seems heavily outdated.
I doubt BetKing in its current trust standing (reference:
this) is representative of the values CGF stands for.
Nitrogensports seems to have some issuse of their own as well, and might have been excluded from the foundation for those. You can quickly find those if you google for it.
Overall, the first reply should be updated to include the current operators that joined after it was last edited, and exclude those that are no longer a part.
There are others good casinos, that have not appeared in the Foundation, such as Bitvest, 777 coin, CryptoGames, FortuneJack, Bitsler, Windice, and so on.
Bitvest & CryptoGames are both featured as verified opreators on the foundation website.
