Note from JWR:

For those that might feel guilty about never getting a voluntary 10 Cent Challenge subscription, here is a new, zero cost option: You can donate your computer’s background processing power to mine Bitcoins for the Ten Cent Challenge. This a Java applet that is NOT installed on your PC or Mac. It simply runs within a web browser session. If everyone that reads SurvivalBlog were to keep that Bitcoin mining web page open while web browsing, or better yet, overnight… It might even add up to some significant digits. The link above incrementally adds Bitcoins to SurvivalBlog’s specific account as soon as you click on “Start Generating”, and will continue to do so as long as you leave the page open. Many Thanks!
