faucets are ridiculous man.. every hour you get a chance to earn less than 1 penny. i did it for 2-3 days or something like that, and ended up with 3 pennies worth of bitcoins.
Yeah, but wouldn't you wish to have earned a few pennies worth of btc a few years ago and the forethought to have kept them?

Anyway, as others suggested, the good thing about faucets is that they allow people who are relatively new to this to earn enough to start playing with it; you won't get rich with it, but that was never the point.
sure, but i'm not quite sure if bitcoin still has enough to grow 10,000% from what it is today. if it were possible, it'd be like 1 cent = 10 dollars. so it'd probably take me a day or two to earn 10 bucks, if bitcoin were to increase by 10,000%.
