a new bitcoin faucet/micro-payment service, captchacoin.com. All you have to do is enter your bitcoin address, hit enter, and begin solving captchas. Users are paid 5 micro-bitcoins (uBTC) for each captcha they solve and need only solve 11 captchas before receiving their first payment.

A quick comparison to other faucets:

    With CoinTube, watching a video gets you 10 uBTC. You can earn the same amount by solving 2 captchas at CaptchaCoin.
    With BitVisitor, spending 5 minutes on a page earns you 10-30 uBTC. This equates to 2-6 captchas at CaptchaCoin. But BitVisitor limits you to around 10 pages a day whereas there are NO daily limits at CaptchaCoin.

Note that those faucets require you to solve a captcha anyway. So really 1 video + 1 captcha at CoinTube is equivalent to 2 captchas at CaptchaCoin.

Anyways, if you're interested, give it a try
