Problem is exactly what you said..mainstream society, which is Most of Society is turned off by all these "microbits" and "satoshi", it's too irregular. I have friends who don't care about Bitcoin but know the basics about it, wanna know why they dont care? Because bitcoin is offputting with all it's math, and the 21million total limit makes it seem as if the currency itself wasn't designed to be thought of seriously.
The math isn't that complicated. Sounds like the problem is with the public education system, not Bitcoin. Instead of dumbing down Bitcoin, perhaps the sheeple need to wisen up.
