Best way of mass adoption is by word of mouth. I personally got 6 people to sign up and start using steemit, that know nothing about crypto nor use it. The user interface on the website is very easy to use, anyone can do it! It's all about hype, just get normal people to signup and it will spread like wildfire! :D I remember when facebook started, you had to get a private invitation from someone that was already on. Why did people initially signed up? Hype and because it was something new.
It's not about the product but of howwwww you sellll it!
