Hi there! Nice post. I wrote an aggressively optimistic post about the blockchain. Feel free to check it out. I like to try to balance myself out with a few grains of salt so thanks for keeping me grounded :)
I think the establishment will back centralized blockchains or create their own to control. That's why I think altcoins like Ripple are safe from government/bank attack. While centralized Ecoins are probably a safe financial investment this likely makes them conversely less ethically sound.
