In my country selling 1 Bitcoin at the current price could make a living, but in some other poor countries even 100$ in BTC can really help people to make their living, so its depend on countries.
That is right. In the US, you need at least 3 bitcoins a month to make a good living. It is more expensive than other countries.
3 bitcoins to make a living in USA everyday? is too high the cost of living there
in my country 0.1 btc is enough to make a living everyday.
