"Perception" by whom? If you think [your] red stone is worth $20k, and I think it's worth $200, what am I going to pay?
...
That is an interesting thought, but works only in a staid objective value system. The land of androids. In our lives, we live by the subjective value system, where our value is proportionately tied to our desires...
Take a new car, for example. You feel that a new car is worth only $20,000, and that is all you wish to pay for the car with the options package you desire. But the lowest price you can find anywhere for that same spec car is $25,000. However, for a plain ol' base model, you could pay just $20,000. (This assumes all haggling has been done by now).
So you hem and haw about it as you have reached a decision point. Pay what you think the car is worth without your options, that would perhaps leave you unsatisfied, or $5,000 more for the car you really want.
If you really WANT that red stone and it is the only one available for $20K, then you will have to fork up the $20K to have it. It doesn't matter what you think it is worth...You will pay what the market price bears. Thankfully we live in a system that embraces competition.
What Baron was pointing out was just the basic supply/demand thing. What Scat was griping about was the crypto bullshit. Both are correct. Cryptos are a sort of bullshit, in that they are backed by nothing but what the market price will bear, along with the added value of their anonymity and use as an actual accepted form of payment between consumers and merchants. AFAIK there's only like 2-3 of them currently being used regularly. bitcoin, BitCash, Ethereum?
Anyways, of course all the rest are just speculative garbage, backed by truly no value...Only by what value the people who buy and sell them are willing to pay each other for exchanging them.
Like the Pet Rock, and bottled Manhattan air. And these days, we have Gwenyth Paltrow selling https://shop.goop.com/shop/products/mini-cuff-sado-chic-chain-mini-o-r-mini?taxon_id=1489
For that price, you'd think the thing is made of palladium. Nope, just a $100 chunk of silver, if that.
