I'm testing this Firefox/Chrome extension for earning Bitcoins, plus referral system, to see how much it pays off.
This Chrome/Firefox browsers plugin is quite respectful of privacy. Now it has also a slider where you can tune the cpu draining of this application, so that if you see that your computer slows down, you can decrease the amount of cpu calculation cycles used by it, or even switch it off.
Referral campaign has started! Prizes are:
1st: 0.3 BTC
2nd: 0.2 BTC
3rd: 0.1 BTC
30 more prizes × 0.01 BTC
