The impetus for such growth, presumably, was the launch of the new veil peer-to-peer forecasting platform built on Augur, 0x and Ethereum technologies.
The platform is operated by Veil International Ltd, a company in the Cayman Islands, and at this time it is not available to users from the United States, Cuba, Syria, North Korea or any other region with limited cryptocurrency legislation.
The market has already corrected and Augur is ca. 35% up. I would also assume that this fundamental is beyond the sharp price increase.
