It will go a long way if we show case money earned from bitcoin to people who don't like bitcoin, there is the need to convince them that bitcoin is real atleast the money earne from bitcoin can be used to pay some bills especially in third world countries were there are low income earners.
If a person don't need a money, we can't convince them to use bitcoin since most of the poeple are using bitcoin to earn not to use its advantage in making easy transaction.
