Have we already seen the full extent of the effect of the Willy Bot news? If it gets more substantiated in some way, would we face more negative sentiment? How did the story affect holders who may have bought based on that perceived buying pressure in the last bubble?
I personally didn't put much serious consideration into the Willy nonsense.
I won't call it nonsense, the analysis of the database is helpful, and one can see the effect of Markus/Willy on the MtGOX price very clearly.
However I don't agree with the author's theory that those traders/robots caused the 2013 bubbles; I believe that the robots merely copied them from elsewhere (China probably) to MtGOX, by doing arbitrage.
That makes some difference on the possible impact of the report.
If the bubbles were created by Markus/Willy, then, after the closure of MtGOX, the price has been holding itself up by its bootstraps, and could collapse at any moment -- especially if the market reads that report and agreees with it.
On the other hand, if the bubbles were due to Chinese demand, then the price has been sustained by that demand, independently of MtGOX, and should stay up as long as that demand continues to exist, report or no report.
