I'm looking to understand how Bitcoin casinos work and how next roll game predictions work?
I think all cryptocurrency gambling sites works the same. The only thing they differ is their transaction fees, Bitcoin and Eth is the big two for that. For how to predict the next roll, I'm afraid that's based on how lucky you are in gambling. There's no way someone could predict random numbers accurately, there's only thing called "luck" for that.
Using Bitcoin in gambling is very expensive in my opinion since you could lose to much profit in the long run. For example if you use 0.1 BTC in gambling that's worth $5,600 could be $8,000 after a year or so if you just hodl it.
The OP should get back here and see his thread. There's a lot of info already and maybe clarify what he meant by that statement. But if he is looking for some strategies or winning techniques, there are several threads already in the gambling discussion board about possible strategies used. However, most classic casino games are based on luck. So even if you want to try martingale or any known technique, still there's no assurance that you will win as you are talking about luck.
