Should be sports betting, if you are a sport lover, you can win more than lose, it means that you will have profits in the long term.
You cant be sure even if you play on sports betting you cant guarantee that it would make you good profits in the long run because as we all know theres no such good profits out of gambling unless if you are really a lucky person then it would be possible.
It will always tell the story that gambling is not for everyone, that's a hell of a job for someone to make money in gambling consistently. Others can make there living in gambling but not all of us, so we need to evaluate our capacity to make money in gambling before we jump in.
I agree, in order to make a living from gambling you must have enormous amounts to spend in gambling. They must study every risks so that they won't get bankrupt easily. Even a CEO in a company or business tycoons does not gamble for a living because they know they can lose fast from it.
