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?
I don't really use strategy when I gamble but when I do I usually use martingale although it is notorious for it's losing profit in the long run
but it can sometimes benefit you if you're lucky but I wouldn't recommend it to someone if they are to ask me for a strategy.
It's hard to use this strategy even you'll use different sites of gambling as there's different system that being implemented inside any gambling house. It's still luck that will brings you the winning combination, you have to settle between being entertain or trying your luck to grow your money from this venue of activities. Most of the time it's just your psychological thinking about trying your chance between gambling house using the same strategies.
