The NFT thing is comparable. I think most of everybody investing understood that they were worthless and that it was a bubble, but there was a remote chance that it wasn't a bubble and even if it was a bubble then you'd still a reasonable chance of making a profit, and even if you didn't make a profit then you'd stand an even more reasonable chance of getting out with fairly minimal losses. Nobody thought there was any remotely high chance of a poor quality rendering of an ape being worth more than a house for the indefinite future. It was just speculation, sometimes poorly and sometimes reasonably measured.
