I comment Bitcoin and Blockchain technology on Disqus once:
"Let make things clear! There can be no Bitcoin without block-chain technology and vice versa. Block-chain controlled and managed is just an ordinary database as Robert Lefebure said before me.
Block- chain is not nice fluidly jazz music. Block-chain is cyber Punk Rock! as Andreas Antonopoulos said once. Block-chain can't play music from shit of paper. He is wild and free and can't be controlled by design. And this design deteriorate greed, corruption, stand of power and promote equal opportunities for all rich and pour. "
And I have to add a few words about FED chairman change in relation with crypto currencies.
I claim that decentralization and no need for trusted middle party is the most powerful feature of blockchain technology. Controlling and regulation of that technology make it inevitably weaker and certainly having something off control is not a thing FED will support ever.
