IMHO, the best Sport to bet it on is the Sport where you're interested into and have enough knowledge about the game, the association, the players, and even the coaches. These knowledge maybe enough to let you analyze match ups and mitigate the possibility of lossing even betting against the odds.
NBA has been a good betting for Sports for me, simply because I can bet like 3-5 times everyday as there are usually 8 games and 16 teams are playing everyday.
So, when you lose from the current match, then maybe you'll win from the next one. Or win them all, worse lose them all. That's the nature of gambling anyway.
Typical gamblers care nothing about the type of game but the chance to win is what they are looking mate and i think that is the main objective of this thread to ask for the opportunity of winning.
No I don't agree since typical gamblers have specific type of games or options they like since imagine you place your bet on the sports you didn't like to see and you just place your money out of curiosity you will possibly lose even if you place a small amount. And as I observe here the bettors here always goes with those games they are familiar with since it gives them higher chances to win.
