I think there are a variety of reasons one might choose to sell.

E.g. sometimes, I buy things from auction houses and then realize I don't really need them. Since I fear that the market is going to take a dive some time during the next year, I offload the card sooner rather than later. I don't try to sell for much more than I purchased the card for, but I wouldn't necessarily fault someone for doing so.

Or maybe someone's financial situation has changed, and they need to sell. Given how much the market is fluctuating right now, its hard to say what a fair price even is. Obviously the market decides as something is just worth what someone else is willing to pay.

I would be a bit annoyed if I sold something for a reasonable price to someone on Net54, and they turned around and sold it for a sizeable profit, but I also wouldn't be shocked.
