This is a great example of a thread that needs closing by the mods. OP's question was answered completely and accurately in the above post.
I'd like to also emphasize that doing faucets might be fun, but it's an awful waste of time if you're actually trying to earn bitcoin. The easiest, safest, and probably best way to earn is via signature campaigns. Unfortunately a lot of the newbies who join them end up actually having to work and have nothing to say. It ends up in posts that are short or complete garbage. OP has probably figured out how to proceed by now, seeing how old this thread is.
Watch out for trading. If you don't know what you're doing, you can get into a lot of trouble very quickly.
