Well, you don't need to be psychic, just understand something about economics.
When you buy shares in a company, you essentially buy a piece of its revenue stream, even if it doesn't go to you. Plus physical assets. There is some incentive for someone else to buy it from you. I mean, if nothing else, someone attempting to take over the company would need to buy those.
Hell, even way back in the tulip craze, you got a physical tulip bulb of some rare variety. If nothing else, you could plant it and get a flower to hold while getting your portrait done, as was the fashion at the time. Or create more physical bulbs out of it to sell. You need one initial bulb to create a second bulb. It wasn't smart at that price in a bubble, but you can see some thought in thinking about it as being an investment.
Meanwhile, crypto was never even that. It was like buying a napkin on which a child wrote "TULIP" with crayons. It had "greater fool" written all over it from day one. It had no value. Unlike tulips, you didn't even need one bitcoin to mine a second bitcoin. The ONLY way to get something out was if a bigger idiot bought it from you for more money.
