I'm more inclined to think it's a bunch of retail people all wanting out. All of the large asks are on the retail MMs. Then we have VNDM showing 10,000 with who knows how much hidden.
I know MMs use the retail exchanges sometimes just to keep us guessing. So maybe a combination of things going on. Sure as shit stinks though, that ask isn't going to get taken with all that weight and a barely existent bid.
