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?
It's a personal choice if you want to involve in bitcoin. If you are not into technologies or just something about gadgets then probably your do not know what all the functions of it. Maybe some people heard about what bitcoin is but they not interested at it. I think professional personalities don't want to involve such things as bitcoin because they don't have enough time to spend in.
