but that's not my strategy.
There is really no legit way of making profit from gambling that much easily. All requires a good considerable amount of skills on a particular game. Your one skill may not work on another gambling type for easy money making. That is the reason most of gamblers do fail.
However your only chance to make really good profit from gambling, you need to win it in very low amount of bets ( big bets ) and stop playing after that, because winning constantly is impossible.
The martingale method is great for small bets with a massive balance, but it starts to falter beyond that.
Sportbetting sure profitable and like you said you need to make many wins to get profit because the odds is low and usually you can win only with small odds. But I wondering why people tend to go for sportbetting rather than dice? I think you can still win in dice with small odds too
