My approach with this at the moment is to mostly buy and hold, probably for a very long time. Maybe that nets me zero in the end, but I doubt it.
I enjoy getting moments of players I like, mostly Celtics, occasionally other players I like to watch and think are HOF caliber but are undervalued like Westbrook.
I got lucky with this pack, I got the Anthony Edwards which is part of the challenge. Sold it last night for $300. I hardly ever sell but I don't care about this challenge and if I really want the Edwards (which I probably don't) I think I'll be able to buy it back (with a better serial #, mine was way up in the 1700s) for under $100 at some point post-challenge.
Probably what I'll do instead is use that money to buy more Celtics moments that I actually want to hold on to, maybe something in series 1 if I can swing it. Or maybe the Zion from the Throwdowns drop.
Prices are down in the marketplace but not "crash" down I don't think. Outside of the wild swings of the challenge moments as they enter and exit challenge status, it's not like I can wander in and suddenly get series 1 guys or superstars for half price. Maybe of peak, I wasn't paying attention that closely, I mean over the last month or two of prices.
I guess I look at this all this way, as someone who has collected stuff over three decades like comics, cards, etc, and has sold at the absolute wrong times and the definite right times, and bought the wrong stuff and the right stuff, mostly because I was buying what I liked -- I think it's unlikely that digital collecting goes away. It will probably have popularity peaks and valleys over many years. But let's say Tatum has a good career and remains popular. Will more than 20,000 people be interested in an early Celtics Tatum moment in 20 years after he's retired? Yes, probably. Same way lots of people would want a Papi rookie and we'd all be impressed and think it was cool in the cards thread.
I still think the real value here will also when they figure out how to go back to Jordan moments and the like. Think about how those packs would sell. Or if you had a cool black and white Bill Russell moment or something.
TL;DR to me Top Shot is best approached as use the least money possible to get players that you like and want to hold long term and eventually sell if you feel like it, years from now.
Somebody necro this in a decade and see how I did.
