Yup! and it will always stay that way, because gambling is risky and as hell you could truly beat the crap out of you, but there are still a chance that you can still profit in gambling because there is a chance that you will be lucky anytime of the day.
of course if you play gambling will definitely get a chance to win, and you would not necessarily expect in luck. especially if you have knowledge and a good strategy. at least it makes a greater chance of winning.
Yes i believe in strategy not much some percentage not in all games only sport betting and poker game here we can use this. But just now i saw there is one guy lost 50 BTC ina single shot in sport betting don't know which method he used and bet tat game but he lost that so now i am thinking if our strategy want to work means we have luck first or else result is loss.
