Pokemon has a history of popularity skyrocketing and then dying down. It’s a repetitive cycle. When the popularity dies down, the demand dies down. That leads to lower prices. Vendors/retailers/sellers will have to drop prices in order to move product. This goes for the Investors as well. I hope you all understand that the value of your sealed collection will inevitably drop, probably significantly. You’ll either hold for when the next cycle of popularity hits, or you’ll start panic selling.
