There are hundreds of pages to earn bitcoins and other cryptocurrencies watching advertisements and advertisements. Every day new ones come out but the problem is that a high percentage of them after a few months close or stop paying. It is true that being totally free page do not run the risk of losing money but if you lose your valuable time.
Personally, I prefer to focus my work and promotion time on a few pages than register first on any new page that comes out. To day the pages which I work, promote and recommend are the following:
Clickcoin. https://clixco.in/r/ElCofreDelDinero
Bitfun. http://bitfun.co/
Bonus bitcoin. http://bonusbitcoin.co/
The operation and use of this type of pages is very simple. You will not need any type of knowledge to start from the first minute to generate profits. Simply click on the different ads daily (or every few minutes in the faucets) visualize them for a few seconds and finally solve a simple captcha to claim the satoshis
