As long as you play at reputable on-line casinos, there's no question about the legitamacy of the outcomes. I've played MANY thousands of hands over the last few months and my loss rate is right on target. And yes, you will lose when playing basic strategy perfectly; that's just the way it works.
My advice is to play at a casino that offers a cashable bonus with a low wagering requirement and make small bets so you don't lose much of the bonus. It's not terribly fun and it doesn't even feel like gambling but it's a good way to make some extra cash. Once you've used up all the sign-up bonuses, you'll just need to get a little creative.
