I have seen gambler who don't have any fucking idea about cricket but he used to bet on cricket.
This sounds like a case of problem gambling, where a gambler can no longer control themselves. What would you know to play when you have no idea about a sport, why gamble on a game you know nothing about, very illogical, similar to investing heavily in a coin you in know nothing about. Such an undergo should undergo evaluation.
Which one are you mostly placing your bets on?
Soccer is the most dominant sport in my locale, i possess a certain amount of knowledge about the game contributed mainly by environmental factors and even physically played soccer at some point, it is what i mostly place my bets on.
I love boxing and the UFC as well, once in while...when there is a major fight, i usually bet there as well.
