How many gambling sites are you playing and do you use the same strategy? I'm playing on at least 4 sites now and uses a different variation on the martingale and some guessing method and I found out that I have good success implementing a method on one gambling site that is not effective on other gambling sites, how about you?
Honestly, i am only using 2 bitcoin casino sites because it is the only sites that i can trust and it gives great bonuses and prizes. I am also using the same strategy when i am palying the game poker because it is also has the same rules even it is completely a different gambling sites. I always used the bluff strategy to scare my opponent for them to fold their cards because it is one of the easiest way to win in the game of poker.
