Well, if your goal is to bring prices back down a bit, maybe 50k is a good idea. I would have said go for something around or a little over 60k maybe?
Maybe someone else who is keeping a closer look at current market prices than me can give better advice though. I usually just auction them so I don't have to figure out prices when I do want to sell one
People who are buying them might have better data (looking at Akili, who usually keeps good track of stuff and won that last auction of mine)?
I think the lowest I remember them to be was 15-20k. That was already pretty nice in comparison to now though... And then I think for the longest time it was 35k.
