Is this a bubble or not?

I am out of pokemon cards collection, in the sense that I do not buy any card but I am quite informed through Facebook groups, YouTube and Reddit. I do not buy cards just because I think that they are overinflated and thus it does not make any sense to buy them now when (hopefully) in some months/years I can buy them at a lower price.

Having said that, do you think that Pokemon cards are a bubble as some years ago sneakers, supreme stuff etc were? Will we ever see cards such as Charizard base set (good conditions) below 100€/$ again? Why
