Hmm a tiny possible-quibble there, as those who hold bitcoins are maybe somewhat out of luck/power if no one wants those bitcoins / is willing to trade things to them for those bitcoins.
So it kind of seems like really the economic power is in those who want to hold bitcoins, assuming such people even continue to exist for any particular fork, rather than in those who already hold them...
(Its in the economy, not the coins, maybe?)
Its in those who hold the economy, not those who only hold the coins?
