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?
If it is a matter of interest then technology as way to introduce Bitcoin might be weak to convince them to join the fun. I'm sure that they are interested in
money right? Well, we can't say for sure that it is money but it acts like that and we treat it like money though the more appropriate word to classify it is cryptocurrency.
Anyone can really use it as long as you are willing to dedicate your time in understanding Bitcoin, have a gadget and internet to access it then you're done.
