If they aren’t replaced by another wave of early 20s with the same conviction in Pokémon cards, then that would also lead to a big retrace.
The multi generational appeal where parents introduce their kids to the games and media creates a self sustaining cycle. Pokemon is arguably the biggest IP by revenue and cultural reach. It’s the highest grossing media franchise ever created. It has already demonstrated staying power across three decades. Few maintain relevance for that long. It’s the definition of lindy effect unlike the examples you mentioned which were a fad.
It’s truly remarkable how little supply there comes up even during a price action frenzy like this. Alot of people genuinely like these cards more than they like hard dollars and that sort of 30 year long attachment you cannot replicate. NFT projects tried and failed miserably because a low capped population of something is not enough. You need genuine interest to maintain the price floor’s over multiple market cycles.
So far pokemon has always managed to create higher price floors after every market cycle and I don’t think this will change anytime soon.
With that being said I wouldn’t be surprised if we tank -50% soon enough but I also wouldn’t be surprised if we 200% again either
