I believe that adoption of the blockchain technology would start from sec and then the public.
The way things are going in cryptosphere with regards to the sec, I think the sec has overwhelming influence over blockchain.
No SEC is going to bring the mass adoption of the blockchain technology.
It is going to start if companies and large organizations will start using this advancement and the benefits of it will start being shown in the real economy. Then, lobbies are going to push for mass adoption and bring the new trend of cryptocurrencies and blockchain into effect.
