I'm a UI Designer and while the tech itself is unique and innovative the way it was conceived for massive adoption it's just nonsense. No common people will bother to learn the decimal value system to begin with. It's completely unnatural.

Don't get me started on wallets, addresses as long as a line of code, keys, brain passwords, etc. Millions will be lost if people actually use Bitcoin. And many more will be lost in non refundable transactions. Xapo did a decent job in "dumbing it down", but it will take much more than that for your girlfriend or father to adopt it.
