Sports Card Strategy: When Should You Buy 2021-22 NBA Rookie Cards?

I've always been a huge sports fan, but at age 40 I'm having the
most fun in my entire life following professional sports.
 Why?  My re-entry into the hobby of collecting sports
cards this year.  Case in point, the 2021 NBA Draft. I
wanted to watch the entire thing for the first time in my life.
 And I did.  And it was super fun.  I wanted to
hear Jay Bilas and the other experts talk about each pick. I
learned that the 2021 NBA Draft could potentially (several years
from now), be seen as on par with the 1984, 1996 and 2003 Drafts.
 I was pumped my Pistons had the first pick and took Cade
Cunningham, but had it not been for the hobby, I may not have
even known about Jalen Green, Jonathan Kuminga and others.
 But the excitement that the hobby has infused into me has
to be perfectly offset by the business person strategist in me
also.  What I mean is, I've been so excited about sports and
sports cards, that I definitely made a ton of purchases on
emotion over the last 8 months, and now it's time to learn from
some of my mistakes.  Well, maybe "mistakes" is harsh. Let's
call them learnings.  Learning Number 1: Topps NOW and
Panini Instant are for collectors only, not investors or
flippers.  Learning Number 2: College uniforms are not
resale (secondary market) friendly.  Learning Number 3:
There are so many different kinds of rookie cards, that only a
few specific ones hold real value. For my NFL version of this,
click here.  Takeaway: I will be reminding myself to be
extra patient, and exercise maximum restraint on buying 2021-22
NBA Rookies. I want them all, and passing on Panini Instant Draft
Night was hard for me, but I'm glad I did.  I will only be
going after Panini Prizm and Prizm Silver versions of Cade
Cunningham, Jalen Green and a few other guys.  I will pass
on Instant, Hoops, Donruss, Select, and a ton of other high
priced Panini Releases.  My money will go into Prizm, and it
will likely happen on StarStock.com (get a free $10 when you sign
up using the promo code "nooffseason")  The proof is in the
data, and after going back in past year's basketball cards, Prizm
is the only brand sure to hold value.  The reason I like
StarStock, is you can get "pre-graded" raw cards. Look for
StarStock A graded cards, as a likely avenue to be a PSA 10, or
SGC 10 or at least 9.5.  This is a safer bet than buying raw
from a peer online not really knowing the condition of the raw
card.  So as much as I wanted to drop the $9.99 on a Panini
Instant Draft Night Cade Cunningham Rookie Card, the reality is
that card would have been super hard to sell for any kind of
profit.
