yes you make my point, they all have a rarity value . That seems to have been the intention of Bitcoin, there is only 20 million, even down to the mining of them.Correct about gold.
Incorrect about diamonds.
Diamonds are not a rare commodity, the supply is artificially restricted by a cartel and the perceived value inflated by clever marketing. Diamonds are simply not rare... there are already enough diamonds mined to meet consumer demand for the next thousand years.
High clarity Emeralds, Rubies and Sapphires are actually rarer than equal quality diamonds.
(Okay so you are 'technically' correct in the sense that everything is finite, but you catch my drift)
That's interesting about the high income fund side of things.
However, if you're nearing retirement age then the value of your pension matters enormously because you no longer have years or decades to wait for the value of your own pension to rise again. Of course, if you can tough it out and not cash it in that's fine. But many people will simply not be able to wait, so any market correction that lasts more than a few weeks will start to really hurt.
Amazing how intelligent people are when they are lucky but how they become victims when the luck runs out.
