If you can live on a dollar a day it's very possible to "earn a living" with bitcoins through the various service on this forum.
That's right, if the cost of living in where you live is just one dollar a day, then this forum would be a perfect source of income.. but I don't see any country that one dollar is enough..
even in 3rd country you can't live if you just earn 1 dollar daily, at least you should making 300 Dollars monthly or 10 dollars daily, and i think you can earn that amount from trading, or offering unique service that related with bitcoin,just saying
