Bitcoin is usually used by people interested in technology. I mean, persons with a certain technical knowledge are interested in bitcoin.
My observations are that way. I think Bitcoin needs to reach larger quantities. Can use bitcoin in people who are not interested in technology?
Can people use the bitcoin in the profession group like tradesmen, teachers, housewives, firemen, butchers? Are we going to see the days that these people use bitcoin?
i think that's is depends with personality and environment support. while their social environment support using bitcoin in daily, maybe they are possible to do that.
although someone are not interested in technology but you just teach them how to use it. i am sure after they know benefits of bitcoin they will join this world and start using cryptocurrency.
