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?
Yes , bitcoin doesn't required any techie knowledge , but requires time , effort and patience. So as long as someone does have that traits he/she can earn bitcoin or use bitcoin.
And i know some in my friends are teachers , housewives use bitcoin in their lives.
