We want to see what the community feel is the biggest blocker for getting blockchain technology up and running. Let us know what you think.
I would say that every answer in your list blocks the blockchain technology mass adoption.
It seems that the authorities don`t want a more decentralized way to store information.They want everything under their control.Sooner or later the banks will adopt the blockchain ,but without cryptocurrencies.
They want faster transactions with lower transaction fees.
The number of blockchain devs will increase in the future,for sure.
