I read some replies, mainly in the Mining section that said mining was a fun hobby for them and not a thing that they could continue doing as a business. In the Project Development section I found many projects that generated profit like your local businesses.
How serious is BTC to you? Could you look at it as a foundation of business/job or is it just an exciting hobby/experiment?
It's one of my productive hobby cause it allows me to earn extra money. If you're asking how serious I am in bitcoin, I guess I am one of those who takes bitcoin seriously because I believe in its potentials that can exceed my expectations in the future.
I have a lot of hobbies but I guess I spend most of my time in bitcoin. And it has helped me a lot in my financial problems.
Enough reason to be serious about it.
