This is going to blow your mind but Exter was on the board of the Federal reserve .    Before the gold standard fell and the system fell into the dark side the ironic thing was that the Federal reserve underlined how solid value under pins more speculative ventures.

Not that there is anything wrong with risk, various debt, bonds and the whole spectrum of variable quality papers of value being exchanged.  The Exters triangle just outlines how the most stretched unclear values ultimately rely on far more boring things as gold.

Thats why its clear gold and bitcoin are not interchangable.  Bitcoin could be great, might keep on growing but its transactional not a fixed asset and clearly its value is highly changeable.    Its foolish to keep all value in 1 asset type, gold is inert and not massively useful but it does function as money for thousands of years now.   I dont disagree with silver or even copper and many other alternatives but they all tend to be more industrial which comes back to flucuation of supply and demand and variable value.   Gold on the other hand doesnt ever change and roughly is supplied in line with population growth, its far more steady in value then most.   Something like 1% is rational allocation, if people cant hold that much they are either not especially wealthy which is fine and normal even or they are not rational in risk avoidance.  Gambling is a common past time but not the good gamblers cash out profits at day end
