I still cannot understand how those big sellwalls gets raped so quickly, like the 27 wall. I would expect that the seller would pull back his order, but no.....it gets instantly eaten

Like I said earlier, all I see is whale blubber.
I think you mistake the intentions of some of them (the smart ones) - we're clearly being shepherded up. When profits are taken though, I think our market cap and momentum will carry us and there will be no big fall, just a brief dip then business as usual again.
This.
That's what I was always saying. A proper pump on a valuable target both make profits for the pumper and helps the target to reach the new floor.
Win-win.
