LOL. Faucets were profitable years before. Now? You'll just be wasting your time and effort. Investment is the easiest way to earn money through bitcoin, as long as you know what you're doing and just investing your money to the trusted projects.
Even a few years ago, faucets were not profitable enough so that you could confidently say that you are earning bitcoins on them. Faucets are designed for lazy people who want to get money for nothing. Nothing in life is given without work and bitcoin is no exception. In order to earn bitcoin you need to work hard and study this area.
Investing is not the easiest way to get bitcoin. To ensure that this activity brings you profit, you need to thoroughly understand it. Otherwise you will lose, not receive.
