No idea how half of the people in the world who sell picks could ever make a living betting their own picks, In-game wagering aside.
I tend to believe that really only a very select few consistently make a living betting sports. When you look at just the 100 game sample advertised so many people are in the red its ridiculous, which is to be expected, but far how long can these people sub-stain the loss's ?
And of there's the others who kill it one yr, and get destroyed the next ... I mean I guess its possible to weather the storm if your bankroll is big enuf, and still somehow pay your bills, and still have some semblance of a normal life while your hemorrhaging cash.
