Hi
Bitcoin casinos works just like any other casinos based on predictions a little bit of mathematics , at the end of the day you have to understand for a fact that they are just like other casinos but you have to understand that they are more secure more private which is much needed at this time because even the incognito mode is being tracked , you literally cannot find anything good and secure.
At the same time the next roll is dependent on the game, if you are talking about the general one it's all based on probability sometimes you can use permutations and combinations to find out if the game is profitable for you or not. Plus you cannot just do anything other than calculating how the next roll might be beneficial for you or no but there are no exact calculations or whatsoever.
