On a related note, there's already a Bitcoin ETF on the Swedish stock exchange: http://xbtprovider.com/

That's actually an ETN (exchange-traded note). But don't ask me what the difference is.

ETNs carry credit risk as they generally dont actually own the underlying asset. Instead, the ETN's issuer promises to stand by the value of the underlying asset.

Historically this was not an issue but the collapse of Lehman Brothers, AIG-FP and others made it clear that owning assets is preferable to someone making a promise to give you those assets.
