many will have heard the word in passing. they won't know what it means. i think it'll be at least 5-10 years before it dawns on a small number of people in global terms.
I think some of the people probably heard the BTC but I guess they don't really know about it for a reason that it is still 'unknown' in the society. Most of the people are tradional and not so techy (technology literate) so there is a huge chance they don't know the existence of it. In my opinion, even some of the bitcoiners are still ignorant in bitcoin especially to those who are new. It will take a lot of time to finally arise and use the bitcoin by all of us.
