Crypto-trade doesn't have as much liquidity as vircurex or cryptsy yet, so I'm going to guess it was either a fat finger or just not much volume which sent the price up on a not massive amount. Regardless the price is still up 5x in about a week. But on price/growth, dvc has been much higher than here - I think now that projects are starting accrue revenue, support and the ideas are spreading - as well as similar for cryptos in general - thinks are looking good.
