Cryptotab – Free bitcoins from your Google Chrome browser.

So I’ve been running this for a while and it seems to be happily generating Bitcoins, and since my laptop spends its life on and running it’s no hassle to be earning Bitcoins while I do.
There is a referral thing as well – They make money by taking some of your earning power. My Macbook’s fan is running quite high when running the plugin but that’s fine if it’s earning!
