I think only the old aged people aren’t aware of the Bitcoins.
Bite me!!! Just WHO THE HELL do you think set the stage for all of today's tech? Ya know, things like semiconductors, IC's, the internet etc??? Folks like me. I'm 67 and have been in electronics etc. since the early 1970's.
Many folks of ALL AGES are ignorant of technology and frankly I've found that today's youth are scarily ignorant of it in that they blindly share far too much info about their digital lives without a care in the world about it.
That was an interesting answer. Can't disagree with that, awareness about BTC doesn't depend on age and even sex, it's all about a person's curiosity, intelligence, and surroundings.
