I agree, it's totally a ridiculous thing choice of profession, it's quite okay if you have something you are doing that gives you money asides from it, but if you consider making it a full time job then you might be disappointed.. starting up a gambling profession isn't easy, it requires time, effort and some capital.. what are my reasons for saying this, you need time to properly analyze games and also put in a lot of effort to do so because people must see that your winning percentage is high before they can think of paying you for predictions..you also need money to run adverts, so it's actually not easy if it's the only thing you plan to do in the future
I have very big doubts about whether it can be called a profession at all. Gambling is an extremely uncertain, risky and ill-considered thing, it is a game, a chance, not a strategy. How can it be made into an activity for earning money? I do not understand how the methodology of such an activity is built, how one can make calculations and know what to count on.
