First off, bitcoins are basically money, no one is going to give you a lot of free money for absolutely nothing in return. Don't expect that.
Secondly, there are a few ways you can make some money. Faucets are half decent for learning the system of how bitcoin and transactions etc work, but you'll get practically no money from this, so be wary.
Trading is good but requires knowledge and is always risky. Similar for investments, like investing in gambling sites, but maybe a bit more secure than trading if you go with the right one.
Sig campaigns are a great way to start,. build a forum rank and then away you go.
