I see your point. At a certain bankroll, one will have to leave the US sportsbetting market for better opportunities with their money.
One of the advantages of trying your hand at the stock market is that, even if you pick blindly, you'll be even (+3 to 7% minus fees) at the end of every year. Betting blindly on sports, you're going to be roughly -2% for every time you go through your bankroll. Make 2 bets a day @ 1% each over the course of the majority of a baseball season and you're going to be -5% if you pick blindly.
