I once wandered through a museum with a modern art collection. Several of the pieces looked like literal trash to me. I wasn't sure if the security guards were there to keep people from stealing the art or keep the janitors from taking the art out to the dumpster :-)

I get it that some people buy it as investments, hoping to find a sucker to sell it to at a higher price. But that just sounds like pump-and-dump to me. Or maybe it's rich people who have run out of fun things to do with their money.

Me, I'd rather do what Elon Musk does. I wanted to buy stock in SpaceX, but it is privately held, so I bought TSLA instead. Lucked out on that one.
