The Jihadi Woo malicious miner problem is something of nightmares for bitcoin but maybe the final test before mainstream adoption nirvana.
One thing Woo (and idiot Ver) may not have accounted for is by centralising so much power around themselves they are now major targets for any variant of the $5 wrench attack motivated by an incentive for control over a $20 billion monetary security system (or its demise) .... not smart guys by any stretch of the imagination. They might want to start spending that "$100 millions" they budgeted on attacking core (100's of decentralised developers) on some high class personal security.
You would think Ver knows enough of the cypherpunk history to know what happened to e-Gold, Liberty Reserve, e-Bullion, etc central actors. If you want to go centralised with your digital money expect to become the prime target for some major league criminals.
They are also underestimating the number of Bitcoin early adopters.... who hold rather LARGE amounts of bitcoin based on Libertarian principles as opposed to economic reasons. Decentralization of mining is a cornerstone principle to them. If these early adopters feel that the Bitcoin network is being threatened by a sense of centralized control (monopoly?) and developer incompetence, I'm sure they won't hesitate to dump the shit out of their BU whatever coins right into the ground.
