I suggest 777coin ofcourse.
It can accept some altcoins too, it's established and known a long time now.
You can create a profile without KYC and they also offer instant withdrawal, use my signature if you want and it'll help me too!
Bitcoin talk gambling site is the best because it gives us knowledge and help us to gamble profitably. In gambling there are allot of sites but we only will have to choose well trust and good website. But as you have to choose bitcointalk.org it is the best site for gambling according to me.
