What do you mean when you say to get a bitcoin? I don't think so,if this my answer will help you or will fix if what you mean. If to get bitcoin,you can get also a bitcoin through by joining bounty campaign and completing the tasks to get rewards.
I think if you want to be an investors then it is important to issue capital but if you are not going to be an investor or free earn then you can earn without investing by participating in bounty and signature campaign, you can earn through campaign and ten invest it into bitcoin so you will make investment without any personal capital. I think it is quite possible to earn even without investing anything you will just have to fix your goal and focus on it.
