i wonder if that wall was suppose to be eaten.. was it all part of the plan? we will never know..
or did the guy had some other trickery behind this move.. i cannot imagine this was not orchestrated with this amount of btc
it defininately wasn't cashing out.
he did not have the time to buy back cheaper..
maybe if he had 60% on bids.. sitting there and 40% (ask wall) it could make sense. but that means he is fucking rich ! :-).
Might have had some shorts elsewhere. Want to cashout? Use the power of leverage to maximize your gain.
But as you say, we'll never know.
