I'm starting to think what will ultimately destroy bitcoin is the concentration of coins from the early days.
Or... alternatively, there will be an uber crash which eventually will lead to stablization.
IF that is the case, there should be diminishing volatility as coin distribution involves market movements instead of hoarding...
Maybe.
This is why the distribution process of Litecoin was done in a fairer manner. But then again there are arguments for and against litecoin.
