The main thing is a good app for Android with min to no bugs, with little to no KYC. And, of course, there is a need to continuously widen the range of sports to bet on. I suppose these are the key to good and stable success for crypto casino.
If a Casino has the functionality to have an app and if the Casino is strict on the kyc ,it is obvious that in the App it will require the kyc from you in the same way. In a casino App you should focus on security , it should always be at the highest level because it is easier for hackers to extract the person's data , this is something that has always been reflected , in fact I have read many articles that there are people who steal their wallet private keys because they accessed their Phones without any kind of permission and stole everything.
But for now, KYC has become a kind of obligation for certain people, especially people who use a lot of money to gamble. But casinos can make concessions for their members who only play gambling with small amounts of money because many casino members are not people who have a lot of money.
Maybe casinos don't need to release their casino applications but focus on developing their sites that can be accessed via people's phones because creating a casino application also requires additional costs. If the casino has just launched, maybe the casino can think about it later because the most important thing is how they can promote their casino to the public.
