Yeah it is possible to earn a living with Bitcoin but for that to happen you will have to earn allot of Bitcoin.
So I do not think that it is possible for everyone at the moment.
every thing is possible in this world but some task are difficult to achieve and some are easy, although it is possible to earn a living with bitcoin, but to me it will not be a wise decision to depend of bitcoin for living, because some time the price of bitcoin fell down so much and it become difficult to trade in bitcoin therefore we should always consider bitcoin as a secondary option.
People who earn a lot of bitcoin on a daily basis does not care for the price drop or anything else happens with bitcoin,
