there are some things you can do to get bitcoins without having to spend capital as a cost to get bitcoin. and one way you can do is to follow the signature campaign activity you can do to get paid with bitcoin. but it seems for beginners like you it is very difficult to follow the campaign signature activity because the rank you must have at least is a member. so for the moment what you should be doing right now is you should keep active in the bitcointalk forum by providing reviews or topics that will raise your rank so you will be able to follow the signature campaign activity.
