But he does have a point. Because what's the threshold in how much of the total supply should be stored in centralized vaults before Bitcoin is considered "a failure"? If more than 50% of the total supply are held and controlled by a cabal, it would definitely not good for Bitcoin from a decentralization viewpoint. That cabal would have the market cornered. Who would want to start a company built on top of Bitcoin under such a situation? The environment could be manipulated against those that want to compete against the cabal.
