If he has more coins ready and is smart he should stop putting up walls for a little while and slowly put them back again on the way up.
If he keeps adding these walls it might actually stop us from going up for a while and he will be forced to market sell or put a new wall up way lower.
Maybe that is what he is doing. He just happens to have
a LOT of coins to sell.
PS: I'm also struggling to make sense of the wall movements today. The seller seem genuinely interested in selling a chunk at this price level. If he wanted to bring the price down he would have dumped. It would have been easy for him to do when we were below $590 imo, but he waited until we were well above $600, and until the bullish sentiment had returned. When/if he removes the walls everything will be ready and primed to go higher (BTC-e is the only major exchange that is behind). This is the best I can come up with

He dont care what the price is today he is selling because of the date.
Now you got me worried. He might know something we don't. If he suddenly starts dumping because this is going to slow we might have a problem.
