There does seem to be hoarding. Perhaps more selling to reduce volatility and additional exchanges like Mt Gox would reduce volatility and increase credibility.
"Animated graph showing from which point in time coins have moved and stayed unused. Analyzed directly from the complete blockchain. You can see some fairly large (+200kBTC) chunks of coins being moved forward at once multiple times around the end. Coins from the first 240 days are barely moving. About half of the coins generated between the 300 and 700th day after the chain started have been transferred forward at this point. 22% of all the coins have moved in the past 30 days."
