Now, as interesting as it is to consider its a bot trying to get top dollar for the asks.. wouldnt it really just make more sense to market sell into the 140 wall? Yes, yes, 66 cents less.. but.. no risk. And, chance of triggering more sells -> lower buy back price.
Might not make sense for a whale, but if I wanted to sell a fairly significant amount, I would consider dripping them out rather than causing the price to drop. Let the robot continue until something else upsets the price.
