I think its very possible to use betting to support your bank account. I mean if you have other ways to generate income its very likely you can reach profitable point at betting so it can feel like secondary wage. I know a colleague who literally bet twice every week. His income through sports betting reached a point where its nearly more than half of its wage. But making a living through sports betting is very risky and I don't think a lot of people try it.
At the very least, one should be an expert in the field. really know the ins and outs of sports, even as detailed as possible. for example in the type of sport of football, like observers who are experts in their assessment of a team that will compete. whether it's from the coach, the players, the formation, the pattern of play, whatever it is, all of which become a reference in an assessment.
I have a reference to one of the observers in my country, the analysis is really cool. whether it's reviewing the coach, players, patterns and strategies. he can analyze it in depth. In fact, he even admitted that he once made a living from betting on football and it worked for him which eventually led him to become famous as a commentator on a football event.
So, what each of us are telling here is that there are actually people who do make a living from sports betting. but, not everyone is able to do it. because to become an expert, it takes a lot of knowledge related to everything in the world of sports. at least, it requires high knowledge and insight and love for sports and not everyone is able to do it. apart from it all. in football betting, all we can do is analyze it to reduce the potential for defeat and increase the chances of victory. but one thing is for sure, we will know the result after the match starts until one of the teams wins the battle.
