Where will value accrue?
Mutually exclusive, collectively exhaustive, non-sovereign stores of value.
1) $BTC -> asset class in its own right; hardness of Bitcoin monetary policy is unmatched
2) Privacy coins -> introduce fungibility (e.g. $XMR, $DASH, $ZEC)
3) Smart contract platforms -> introduce programmability (e.g. $ETH, $DFN).
Examples?
1) $XMR -> changes to the PoW algorithm
2) $ETH -> changes to the inflation schedule.
