The advent of buttercoin is in my opinion one of the best fundamental movers now.
Buttercoin was on Bloomberg TV the other day, but it was better explained on Let's Talk Bitcoin (or was it Plan B). They supply a mostly complete exchange, all you need is basically a bank account and your own exchange name. They even supply seed liquidity, and all buttercoin exchanges in a country trade on the same order book.
I agree. It's also Y-Combinator backed (Coinbase is too), which gives it a lot of tech world credibility. Having the shared orderbook within a currency is super key.
