The things you should concentrate on when you are looking for a good online casino, has to be the following :
1. Good reputation
2. No Hassle deposits & withdrawals
3. Good 24/7 Online Support
4. Chat feature (Social)
5. Good promotions
6. Good Rakeback
7. VIP Ranking system that are linked to rewards
8. Fast Servers for a good gaming experience
I find that I get this with Stake.com / Rollbit / Roobet / Duelbit.com / Bitcasino.io and Primedice

Wow I think there is no better description, it should also be noted that all the sites you name have always had the good intention of showing their millionaire winners, both stake.com and bitcasino.io when you enter their threads whenever there is a winner with a good amount they congratulate him, in the case of stake.com they sometimes show up to the TX of the winner's transaction, I think that more confidence than the one they show shows the transparency of the casinos.
They are also casinos that when you read their threads, there are many people who live according to their experiences and make everything look like a big family, nothing more than this gives confidence, security, everything you look for in a casino.
Among all this I thing - first three are the most important of all. Online sport is most important of all incase one gets stuck. I always look for that feature while selecting a business.
Rakeback an promotions are indeed what they need to offer for the players to love their site and for the players to stay longer.
and also the VIP thingy though I never reached that rank as I am a small time player lol.
