I think if the world ever gets back to normal and people start traveling and going out again regularly it will slow down some. We for example cancelled a Disney trip and another vacation to the tune of about ten grand. People are bored and cards are a good distraction and can be done from the comfort and safety of home. I also think there is a faction out there of rich folks making it cool to invest in cards. After the dust settles it'll be like any other collectable market and a lot of folks will move on to something else much like the junk card era or other collectable/investment booms. Vintage will always hold value especially the really cherry stuff but I think in time the hobby will correct itself and this current insanity will run it's course.
