The blockchain has a major scaling issue. The more you distribute the harder it is scaled with security.
2nd layers, like sidechains and plasma can partially solve this but as more scale and performance required by demand the more place you have for banks and trusted organizations.
The rise of crypto is not inspite of regulation rather because regulation is adopting the technology.
Like all revolutions eventually the dynamic creates a new order, but it is more likrly that banks and organizations will exist in this new order as long as people perspective is wiifm.
