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?
Since I don't have any plans to open a business or anything then bitcoin is not as serious to me as it may be to other persons, but that does not mean I take it lightly since I recognize in bitcoin a fantastic and revolutionary concept that may change the world.
