any thoughts why nendoroids have dropped resale value?

have been collecting nendos since the pandemic (around 2021) and the prices are around $60-$70. i remember so well coz my broke-ass could barely afford them.

i stopped for like a year (2024) and when i looked up nendoroids again, i noticed a drop in the their resale value. i think some of them dramatically dropped down to $20-$30.

any idea why this is the case? kinda afraid that they’ll go bankrupt or stop releasing some of the less popular characters…. i’m still hoping for a Scarlet Witch nendoroid as well as Ray (TPN).
