I guess the fact that Dooglus was fully divested means that for some reason I personally cannot understand he "lost faith" in math, and he gave up on the idea of recouping losses from Nakowa. Maybe that was one of the reasons he decided to mess up with our best customer ever, while crippling the expected profits by taking max profit to 1/4 while investors that didn't divest were on HEAVY losses.
Site owner has much more to lose than average investor, so his decision is understandable. Besides, there is always a non-zero probability of a bug or a server hack, and whale's win streak odds were quickly approaching that limit.
