What is cryptocurrency faucet?

 

Cryptocurrency faucet is a reward system, in the form of a website or app, that gives out “free” coins in exchange for doing a simple task, such as clicking on an advert, solving a CAPTCHA, or viewing a webpage for a certain amount of time.

The first faucet was developed by Gavin Andresen in 2010.
