At today’s higher bitcoin prices, the hole is growing faster. About 900 new bitcoin a day require most of $45m a day in electricity. Thus, the negative sum in the bitcoin game is in tens of billions of dollars and rising at over a billion dollars per month. If the price of bitcoin collapses to zero, the gains of those who sold would fall short of the losses of holders by this growing sum. To liken bitcoin to a Ponzi scheme or a pump-and-dump scheme, both basically redistributive, is to flatter the cryptocurrency system.

To conclude, an economic analysis of bitcoin must recognise its uniqueness in the history of manias. As an object of speculation, bitcoin is unprecedented in the degree to which there is no there there. This post-modern mania features big prices for entries on nobody’s spreadsheet. A zero-coupon perpetual has arrived not as a joke but as a trillion dollar asset. Unlike a Ponzi scheme, bitcoin cannot end in a run.
