The only method i know which you can earn a good amount of bitcoin is the signature campaign. The only investment you need here is time investment and knowledge but there are some ways like micro earnings such as faucets but i will not going to recommmed it since it just a waste of time (for me) so as long as possible just focus on signature campaign and you'll never regret.

That is the wrong attitude if you are desperate you will not be able to do your best when it comes to bitcoin and you may fall victim of the many scams going around on the web, like HYIP or others, so get rid of that attitude of trying to earn bitcoin fast because that is not going to benefit you in anyway or form but take the time to read the forums and take advantage of the opportunities to earn money that appear everyday here in the forum.
