I can't .  I have to reach for the restriction of supply by the self-interested Masternode Cabal, and the money coming into the centre being spent rather effectively on marketing (and pumping up the price) as an explanation.  One feels that ultimately the Emperor must be seen to be naked, but it's been holding together so far, there are still no cracks appearing in the edifice.

It's not for purists or savants, perhaps - but this market is not filled with purists, it's becoming filled with sheep looking for shiny things to follow that never stop increasing in value, irrespective of their true qualities.
