Quote from PAPA ROACH:
The deeeeeeeep contango is evidence that the market is very oversupplied and storage capacity is running thin. Storage may not be full, but the people that own rights to the storage are keeping them.

Also beware that leveraged ETN's such as DXO do not have the same fiduciary safety that ETF's have. So if Barclays bank goes belly up much like Lehman did, you could see your position in DXO get wiped out as the ETN would likely become defunct.
Personally I'd stick with ETF's such as USO. If you want to employ leverage, just trade options on USO or just trade the actual oil futures themselves. IMO stay away from the leveraged ETN's.
