But perhaps his appraisal was near to some threshold and some events pushed him over the edge and he decided to force the XMR community to prove it is worthy or insolent. Just one possible theory for the chain of events.
Remember Risto issued the 4 - 8% proclamation of the likelihood of a BCX attack while the 72 hour deadline was ongoing. One could ponder if this might have caused BCX to not call off the attack. There was some progress on trying to find any vulnerabilities, so perhaps one could ponder if he might have called off the threat citing progress and cooperation.
But just five posts up he says he's still attacking? I mean if we are guessing that he called it off for certain reasons and make the assumption that our guesses are more accurate than his stated intentions within the last few hours isn't that a little insane?
