I'm looking to understand how Bitcoin casinos work and how next roll game predictions work?
Bitcoin is a relatively new thing and it can be very difficult to understand. There are literally casinos popping up now...
If anyone has any information on it, it would be much appreciated.
I believe that you are mixing up things badly.
Bitcoin is money. Just imagine it as another country's currency, to keep it simple for yourself.
There are plenty of online casinos popping up over the world. Some use Bitcoin, some use VISA. No big deal.
Now, I'm not sure what you mean by "next roll game prediction" and I'm not sure if that's related to Bitcoin. Some casinos rely on (more or less) random numbers for their picks, some casinos may rely on something related to Bitcoin's blockchain (next block hash) but that's so seldom I don't think it's what you mean.
All in all, please ask more exactly what you wan to know.
