So far, I like dicecoin.io
LOL. To tell you the truth, that is the stupidest thing I've heard for a gambling strategy. Your previous bet does not affect the chances of you winning the next one. No bet is correlated! Even if you do martin gale or any strategy, it won't change the chances on each roll. That's just stupid. So for example, I tried lossing 10 straight on 1 sat bet, will that ensure I win 10 times in a row after? No!
True! Each bet is independent from each other and the result is always random. the thing here is that house edge kicks in making the roll inclined or favorable to the house. And there is no 90 %or 80 % guarantee method since all rolls are random and dependent on the internal setup of randomness of the game. Though you can check the hash for possible manipulation but I believe reputable casino are provably fair.
