We can always see that one. History repeats itself. All I can say is we are just a developing community, roughly there are only about 5% of the population knows about cryptocurrency, how much more? 
I believe it's likely closer to 40+% that knows about Bitcoin (and thus, crypto). However, it's likely closer to 3-5% that actually have some sort of stake / position in a crypto asset(s). Clif High's noted many times that at some point towards end of Feb through April, we'll be hitting the start of the ol' tipping point, which may lead to increase that total percentage rather quickly throughout 2018 to 10%+. Who knows though, eh? Stay seated in the roller coaster and we'll soon see who's right, though! Just don't forget to hold on. It's gonna be a helluva ride!
