From my recollection, this early hat history conversation goes back before October 15, 2018 - because I believe that the main reason that V8 was razzing Hairy so much about hat eating was because months earlier Hairy had said that he would eat his hat if there was certain BTC price movement.  I can't remember exactly the bold prediction, so I went back and looked at Hairy's posts for many months before October 15, but I could not find such post.. so I cannot exactly refresh my memory with an actual post.

We are bottoming. If not this week, then next week.  I’ll eat my hat if we are still bumping $12k in late January.

Peter R:  take your shitty altcoin somewhere else.  Maybe the Ripple fools will buy it.
