The overwhelming majority of highly intelligent people I talk to still have no idea why Bitcoin is valuable
.We are extremely early. The ability to identify opportunity before others and take advantage of the information asymmetry is key.
Getting something like bitcoin to the mainstream is not that easy given the fact that there is no advertising budget and campaign for bitcoin similar to big corporations and well-oiled organizations can do. Since this is a decentralized kind of a beast, no one can claim its ownership that is why in the very early days bitcoin spread from one mouth to another. Right now, there are already many in the mainstream media that can pick up news on bitcoin especially if there is a bull run just what is happening right now...
I could not cite some statistics but it is safe to assume that majority of our people are not yet into bitcoin though a big percentage may have heard of it in the media so if one is into investing then the field remains to be wide and open for anyone to participate. Of course, one has to do his own due diligence and then understand that there will always risks involved. Good luck.
