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 would be hard for people who are not interested in technology to learn about bitcoin. Especially those people who are not computer literate. To earn bitcoin, you must have at least a little knowledge about computer, because without it, there's no way you can earn bitcoin.
