CoinWorker - Complete task to get BTC

CoinWorker lets you earn bitcoin using only your web browser.

Step 1: Introduce yourself.
Register and then enter your bitcoin receive address. 

Step 2: Think a little.
Earn points by completing short analytical tasks which can be done in your browser. 

Step 3: Profit!
After your account hits 200 points, points convert to bitcoin (as if USD cents) and are paid directly to your address, usually within minutes.

CoinWorker is like a bitcoin faucet you can pump with mental effort. Or mining with your own mind rather than a GPU.
