You can earn some satoshis with faucet, its free all you need is internet connection.
But faucets need lot time to be spend to earn a good amount. So as a beginner one could start with faucets then can move on to signature campaign as well other earning methods to get good earning.
Faucets is good but it is time talking, i also started from faucets but my internet speed is not good, so i left it.
Starting with faucets is better and also it is easy way, but it is not permanent way of earning, than choice signature campaign, it will give you good earning, also later on when you have earn 1 bitcoin than start the other investment or trading, because in this way, you can earn more in a month.
