I mainly bet NFL football.  I will throw in a little on the NBA and rarely, though on occasion I will throw a few satoshis on Major League Baseball.  I've been betting roughly 5-8 games a week, spreads and money lines, for about 12-13 years now.  I've yet to have a season where I've ended up in the red.  Now, do I have great years , year in and year out, no.  Often times I'll be up just a bit by years end.  But, I've yet to have a losing NFL betting season.  I'm too much of a pussy to bet heavy and never will, despite my success.  Anyways, I'm sure my streak will end this year now lol.
