On the internet there are sites or click on advertisements where most of these sites are scams except some as NEOBUX or PAIDVERT and in addition to reach the ONE dollars it takes weeks .et there are sites to win BITCOIN like the faucets and the trading and also the mining sites are the favors for the moment but with the increase of the prices of bitcoin in the market its sites become impéables or the gains become difficult or will be very low, then they do not become profitable and surely you have seen that you do retreat from its sites that the fees become big.
there are other sites that can frequent but which are very profitable and that I advise you to visit them; instead of winning ($, btc, euro) to look for sites where you can earn money you can easily make investments and earn a lot because the ruble costs less than dollars and bitcoin and even the euro and the ruble gain is very easy as you can see in its sites for example.
