1. How hard is to create and operate casino that doesnt have any kyc verification and still be legal?
Very hard and very unsafe.
When I say very hard.
#1. First, if you're operating a licensed casino there are scammers out there trying to get you, with a no-kyc casino that's not only doubled, but I would say quadrupled. You need to have a separate process, team and methods of managing those scam accounts.
#2. Second, the lifespan of a non-kyc player ranges between a few weeks and a few months, with an occasional player staying longer, while legit kyc'd players stay with the casino in the range from 8 to 14 months.
#3. Third, you need to operate without legit business oriented bank accounts and all your services have to have a no kyc policy (wallets etc), which means that you're open to vulnerabilities
#4. Last point, the pool of good quality services diminishes, whoever is legit and works towards an evergreen future in this business has all of the certificates and licenses, you can't build a team of 100 talented people on wobbly no-kyc legs, all of these people and their families depend on you.
2. Can you add any coins you want on casino or some of them are blacklisted and not allowed, if so please write the reasons why?[/left]
You can't add a single coin (I mean, if you're a one man show and try to do a no-kyc casino and you're basically just adding your wallet and manually approving everything, then sure, you technically could).
You can add payment providers who then either have a set of coins that they have in the package, or you can request additional coins on top of what they have. However, I've tested it out and most people just use a handful of the most successful coins, everything else is ignored.
However, the stronger the payment provider is in terms of security, warranties and coin selection, the more KYC they want. Again, no legit business wants issues with the law, and especially not FBI.
One of the issues of this "no-kyc service" rule is that most of them just end up a scam, and you can't build an evergreen company that will last 30 years on such practices. Just look at the mixer situation that we had on the forum.
I might be wrong though, but for me to change my opinion I would need to see a no-kyc money service that has been around longer than 4 years.
Additionally, from my experience, most of the players who ask for a no-kyc don't understand what a casino is for, and either try to launder money, scam the casino or any other weird combination that I'm not aware of (mix the coins?), so this is why building a whole business on it doesn't make sense imho.
Be very, very careful if a new unlicensed casino pops out and says "no KYC".
