If I am earning more then my present job then I would think of getting full time on bitcoin, but its really hard and risky decision to make.
Ha ha ha.. I always thought of Bitcoin as a side job. If you just run the miner, sit back and watch your earnings grow. It's like you're working but instead the miner is doing all the work for you.
Else join in any signature campaign make the good profit from that as well.
A lot of Bitcoin comes down to it being a more passive income rather than something that should be treated as a job, unless, of course, you really want to make it into a job.
I wish I had a miner, but there is no way that I can actually afford that kind of investment, and I'd probably break it too.
