I have never said anything else. Some libertarians in the past have speculated that you could buy pizza with bitcoin and there have been examples of merchants accepting payment in bitcoin but because it doesn't scale, it will never be an everyday currency.
The use of the words "greater fool" are meant to imply "ponzi" but all it means is that someone buys something primarily because they believe that they will be able to sell it at a higher price later on.
This "theory" can also apply to real estate, some stocks and (of course) collectibles. This is especially so if the price of the item has been bid well beyond what its value as a utility might be. The "fool" aspect only applies if it is inevitable that at some point, the price of the item in question will collapse permanently.
Understood. There's a continuum between 'secondary market' and 'greater fool' and in my opinion, it's about whether it's adaptively managed and revenue generating, ie does it 'make money' and if it doesn't suddenly, are there people at the helm who can right the ship. Stocks are pieces of ongoing businesses, they make money. Most real estate makes money. Collectibles do not. As such, I categorize BTC as a collectible or currency.
Generally, my pushback on the BTC discussion is isolated to claims that it is an investment (as opposed to speculation), and that it's a superior currency. It's a garbage currency, although it has a niche in the dark web for illegal transactions, because the utility of easily accessible anonymity creates value over many other currencies. It's the easy access that's important: gold, diamonds, &c could do the same, but it's a hassle for microtransactions.
But yes, out in the massmarket, it's an inferior offering. And especially right now. Who would buy a pizza with BTC today if they genuinely thought they could buy two pizzas with the same amount next Friday instead? This is what damaged the Japanese economy for the last 30 years: currency deflation is an economy killer.
The defense of BTC switches back and forth about claims of it being an 'investment' when it's rishing; but when it's falling, the discussion pivots to it's 'the future of currency' - realistically, the magnitude of value fluctuation in and of itself tells me it's ***** as currency, and simultaneously, that it's not investing either, it's speculating.
Which is not an argument against participating - just that the participants hopefully are not fooling themselves, and also not misinforming others about what we're dealing with. It's beanie babies, just admit it, and keep on trading. There's money to be made in arbitrage and guessing right. Personally, I prefer blackjack.
