Bitcoin 2.0: Sidechains And Ethereum And Zerocash, Oh My!

“…the Ethereum people sold their own made-up digital currency for someone else’s made-up digital currency, which will now be pegged against more new made-up currencies? And people trade cold hard US dollars for these? This is snake-oil nonsense! “

The Ethereum guys are smart and committed. It’s the digital currency aspects that I have a problem with. Wherever I find it.
No convertibility, no parity.
