Since the regulations and the limitations in the bitcoin exchanges, players care a lot about the Geo location, term and conditions and if they are OK or not to play
Basically it comes up when the players wants to cash out and they can since their country in listed as not approved in the T&C
Support is also important, we have to look back to this point, I agree that live chat is a game changer for new players.
Thanks for your advises

Are you going to release which non-provably fair casino paid you for this "research"? Funny, just looked at your site and you represent two clients that are NOT provably fair. Ultraplay does not provide provably fair games, and select SoftSwiss games are provably fair.
Edit 2: Just looked at your clients page (not just homepage), and seems you are affiliated with a lot of shady casino operators including the following: mBit (cheats users on bonuses), Fortune Jack (fakes volume), Cryptsy (not gambling related, but self explanatory), Betcoin (doesn't pay out jackpots), Cloudbet (only provides Betsoft games --> scam), and so on.
Every major Bitcoin site is provably fair: the ones that are not meet all 3 of your criteria you listed. They have elaborate T&C's that allow them to confiscate user funds from the bonuses they give their players, and they are all "licensed" (the countries they are licensed in do not provide any legal benefit for the vast, vast majority of players).
The whole exchange thing is also irrelevant. They don't care if the casino it comes from is "licensed" or not. CoinBase for example will ban you regardless if you have deposits coming in from addresses known to be affiliated with casinos.
Edit: I would also like to know how you conducted this "research", and with some cites, otherwise I am changing the neutral feedback I left you to negative. Trying to mislead players is not cool.
You seem to know a lot about the casino's yourself, Where is it documented that Fortunejack fakes volume? I will look up mBit not paying out customers now also, I was planning to signup there soon.
