So, from reading all of the replies, I can conclude that these methods might be the best way to earn Bitcoins:
-Signature Campaign: Get to a higher rank and get about 0.1 BTC a month
-Gambling: All depends on luck, I might be able to earn a lot of BTC, but can lose everything
-Exchange/Trading: Exchanging (altcoins, wage, etc) into BTC or vice versa until I can get a profit
-Service: Having some kind of service that accepts BTC as currency
That's what seems like some of the ways. I'm already in a Signature Campaign with 777coin, so that's one way I'm earning BTC. Gambling... well, I've lost some. I don't think it's a great way of earning coins. Trading, I'll look into that. Service, I'll also look into that.
Thanks everybody for helping all the other newbies out there, including myself! Big ups!

If anybody has anything else other than the ones already mentioned, go ahead!
