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?
first there needs to be some place they can "use" bitcoin at. if we want to talk about usage. then if there is a place to use bitcoin just the way there is a place to use credit card, even if "regular citizens" don't understand the technology behind bitcoin they can use it with their phone Apps, with their third party services that make it easier and so on.
We live in the technology. I asure that future will be easy for our daily life. Bitcoin, i think it spread everyday so even ordinary people willing to know about the usage of bitcoin.
