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...
Unlike your traditional casino, bitcoin casinos are not generating the next game roll prediction randomly but they are following some algorithm which will be verifiable and fair for you and gambling house themselves. It means the next to game roll prediction is not a manipulated one hence you can assume that you are playing in a safe environment.
Both bitcoin and bitcoin casinos are not newer anymore but people who are recently adopting cryptos might find them too strange. Fortunately you people are having lots of online material unlike my earlier days. Just find time to google and learn.
