Free bitcoin is a really nice source of a small dust every hour and every day, even for the people that earn a lot of satoshis per hour. It just doesnt take a lot of time to click one captcha every hour, so if you would like to do this 10 times a day through 1 months, it would take you already to a decent amount of sato made just from completing 10 captchas a day. After all, you get a lot of different bonuses which might be very useful for doing such an activity.

But i still cant believe that once a time, when i was at BTC, one simple freebitcoin click was like 150-200 satoshis O.o! now its only 30 sat per 1 captcha.
