So as of this moment, I'm only earning bitcoin through a signature campaign here on bitcointalk forum.
How are you earning bitcoin?
I have been earning bitcoin from signature campaigns for the last 2 years. i also earn bitcoin form my gardening company, i offer a 10% discount for customers who pay their bills with bitcoin. it has worked out well so far as the bitcoin price has went up.
Its good to know that you are surrounded by people who are aware about bitcoins and using it as scenario is not the same everywhere as still there are very few people who have heard about bitcoins and even I am earning from signature campaign since long time and the earnings have become more valuable as price is going higher.
