Anyway I don't like gambling too but I've made 300$ once. Then I got hacked and lost 100 dollars but anyway. Lost around 200$ for all time at gambling sites which I made from trading.
But if we will talk about csgodouble I'ld say it's the best gambling site coz it's one of few sites which helps traders. Exmple: csgostrong/csgox2/csgopolygon. All have withdraw/deposite fee which is really annoying to traders. And csgodouble allowed all traders to change their skins to whatever they wanted w/o any fees.
I'll miss you csgodouble... :c
