May not be fast, but it is Free

I really like FreeBitco.in. I like that it works in multiple ways. The primary feature is that every hour you can "roll" for bitcoins. In addition to the bitcoins, you are also getting 'lottery tickets' and 'reward points' for each roll. The best thing - in my opinion - is that you also earn interest on the bitcoins in your account. From the site: "Daily interest will be calculated at a random time everyday @ 0.0109589% per day and rounded down to the nearest satoshi." You can also deposit bitcoins that you earn from other sites into your Freebitco.in account.

You can earn at home!

NeoBux

NeoBux is a PTC program. In my experience, I have seen over 200 ads per day that offer $0.005 each  plus around 40 ads at $0.001 each. 

ClixSense

ClixSense used to be a PTC program. Since PayPal has dropped it from its service, ClixSense has become mostly a survey site. Since the change, I have earned more cash daily than what I was getting on the PTC days.

EasyHits4U

This one is really a traffic exchange program that you can use to promote your other pages.  However, they also pay you to use it - $0.30 for every 1,000 sites surfed.  Payout is at $3.00 upon request.  It is also possible to win cash, credits, and banner impressions on the many bonus pages.  You also earn $0.10 for each referral.

MyPoints

MyPoints isn't really a cash-earner - more of a cash-saver. It is well named as MyPOINTS... There are several ways to earn your points - complete surveys, watch videos, use their search engine, and play games. There are also emailed offers and a daily poll that helps to accumulate points. You can then exchange those points for various gift cards from shops and restaurants like Amazon, Target, Walmart, Starbucks, Buffalo Wild Wings, an Olive Garden (just to mention a few). You can also exchange those points for up to $100 to PayPal.
