Bitcoins my good men and women. I've set up some bots which run through all available free faucets and cash out for me. I've set it up, and I don't have to think about it ever again. With it, I make roughly £500 a month, and considering I don't pay for electricity, it's allllllll profit. However, since that isn't very worthwhile for people who don't have the same amount of computer power I do, I'd suggest looking into some survey sites like Swagbucks, or maybe some writing jobs. Heck, as long as you have something to watch while you do it, you can get a job filling out captchas for other people!
