Bitcoin faucets are sites, that provide out a small amount of Bitcoins for visitors in return for doing a captcha or process as referred to by the web site. Faucets are a great way to help introduce new people to bitcoin. The system does this by giving participants some quantity of bitcoin, known as Satoshis. Satoshis is equal to pennies or cents of one full bitcoin, which is a hundredth of a million bitcoins. You get these rewards by performing various tasks on an app or website, either by playing online games (most recent) or by filling some captcha.
