Wow, that's something that I haven't thought of before. I agree with some of the comments here that as of now, the market is still very volatile, so it's better not to risk investing your whole life to bitcoin. Right now I'm free mining/collecting bitcoins on the side, but I have a full time job that is my main source of income. However, we never know where the tides of the future take us, and bitcoin might become really important in all aspects of our lives. By then, everyone might be working for and transacting in bitcoin.
