Before calculating your profit loss you should first check when this post was posted. It was posted more than a year and that time BTC prices were not so high and now mostly you will not get the same amount which he has posted. Because all these free faucet money will be adjusted to the current BTC price. You will never get money as per your calculations.

it was earning btc and i think much better than those social media campaign like
twitter or facebook and much more than captcha encoding too.it this all are true
well this is the time for those low compensated here to have some good bucks
