The absence of a secure and user friendly wallet is the killer of mass adoption. It's been that way since day 1 of blockchain. Unfortunately, blockchain - all of them - are technocratically led and thus have little awareness of what mass market is about.

I don't think that's about to change soon. I see some awareness in a few blockchain communities, but overall even those that understand this lack do not have the widespread support of their communities. To many technically savvy believe that the private key is the beginning, middle and end to the question.

The private key may be the middle. But the beginning and the end is the user.
