I added my comments to your list...

-Provably Fair - it is a necessity, not a feature anymore
-Secure funds storage with Cold wallet etc - isn't every service says exactly the same thing?
-Secure website, tested by a computer security expert - every casino is  advertised as totally safe, until it isn't
-Invest option - Play as the house! (1%) - good, but not unique
-TurboBet option - and what it is exactly?
-Friendly interface - again, it is a must
-Hall of legends - nice addition but not exactly top priority feature
-1 cryptocurrency available: BTC (maybe LTC, DOGECOIN, ETH) - nice
-Active support - every casino tell
-Friendly chat - well, you can guarantee that we encounter some toxic people
-Mobile version - standard
-Rain for actives members - you can't guarantee that
-Contest each weeks - nice
-Registred gambling license from CostaRica (coming soon) - it might also be a minus, as more regulations usually mean more KYC
-AutoBet function
-Hotkey function
-Earn badges-levels in your profile account - unless they are linked to monetary gratification then no one would care
-Faucet: 500 Satochi, every 5 minutes - very generous compared to other casinos
-Instant Payout, min: 0.001, no fees (No questions asked!)
-Instant Deposit "0" confirmation
-Instant registration and start betting! - watch out for some exploits here
-100% Anonymous playing - this might be tricky
-AND MORE!
