PSA10s will always have a market, no matter their price, because a rich person will always be willing to pay a premium for a perfect card.
But 9s and 8s? The higher they get the less desirable they become. Why would anyone with money pay such a huge premium when they can just get a perfect card by spending a little bit more? And why would a person without cash to burn spend so much on a non-perfect card when a psa7 is nearly as good?
If you aren't buying 10s, you may as well hold raw.
