The way the buyer acts here another 100k is probably not a huge issue but my point was that he could get so much more for his shares if he breaks the sell orders up, I mean the ask is really thin relatively. The fact that somebody immediately took those 73k shares is another sign that this could have a lot more legs, not sure why but somebody seems to want to buy up the entire float, slowly but surely.
