I have the same doubts about Bitcoin. If it's treated as an asset and not as a currency for exchange of value, how is this going to change the world? Is this expected behaviour as we humans are greedy? Or is this a failure of the system?
If... that's exactly what its being used for unless its being used to purchase illegal goods (ala silk road - which i have no problem with) but as a normal currency in the western world no one is going to adopt it so its an asset until it vanishes.
