Right now, it's just a lot for your average person to understand/figure out how to buy bitcoin. It seems easy to all of us, but when I talk about it with other people, they get a sneer and look at it like it's some sort of scammish fad...
I talked about it with my father, who is in his 70's, and when he heard that you have to buy the currency from another person, not a financial institution, it was like someone standing behind me started waving a banner with "scam" written on it. Even though older people have been scammed by the system many times, they would still support it over this mysterious computer network made by some youngsters who don't know real life... Somebody said that we aren't ready for
BTC yet and he might be right.
