There are several websites that will pay you in bitcoin if you watch an ad or click to a certain page containing ads. If you are ad immune and want to make quick crypto buck–this can be a good idea. Bear in mind, to make any significant money is still very hard work and a rather tedious task.  BTC4ADS pays around 100 satoshis (0.00000100 ฿) and Coinadder pays around 25 satoshis per click.
