That's true it depends on an individual how he views it, different people hold different perceptions towards bitcoin, and no one can change it.

The concept you have chosen is higher then your level of knowledge, you should pick something easier for now because you are new to bitcoin.
You should start with faucets, while using faucets you should keep reading articles or read posts on this forum everyday to get more and more knowledge about bitcoin and after when you get enough knowledge about bitcoin then try to pick up such questions and you will find it easier to find the answers.

You can see more information's about signature campaigns here : https://bitcointalk.org/index.php?topic=615953.0 . You won't be able to join or gain a good profit unless you have higher rank (Senior Member or above would be good) .
As for what comes to Faucets , It's totally waste of time since you spend a lot of time + you don't earn something big .

It's probably not profitable anymore as it used to be and please stay away from "CLoud mining" because most of the services that offers that are scamming people .
Unless you have enough money to make a huge Bitcoin mining farm (which I suppose you don't since you asked this question) It's not really recommended to get involved;
