One of the most profitable sites that give free Bitcoins is undoubtedly http://bit.ly/ViewAdsFaucet
In one day you can earn more than 1000 satoshi without any problems.
There are 3 earnings options to choose from:
- Surf Ads
- Active Window Surfing
- Autosurfing
Autosurfing speak for themselves - clicking this option will open a new window where paying advertiser pages will appear immediately. Just leave this window in the background, new websites will be displayed automatically.
Active Window Surfing means that the advertiser's website will appear in the active window. This window must remain active for the minimum amount of time to display it. Then you can close the window and click on the next link.
Surf Ads is the most interesting option. New and new advertisers' websites are constantly available. Most paying websites are offered first, so you can be sure that your time will be used to the maximum. Click on the OPEN button. This button can be located in any part of the screen. A new window will open with a webpage, but you can forget it immediately, it is not necessary for this window to be active.
Fortunately, annoying CAPTCHA is not required before displaying individual websites. It was replaced by very simple mathematical solutions.
