Yeah, by doing this so publicly, I'm basically ensuring that the price drop happens BEFORE I sell, rather than my sell causing the price to drop. If I had sold privately, the price would have still gone down, and nobody would have known why until somebody noticed in the block chain that J.R.'s coins were being sold, potentially causing a HUGE panic.

It seems clear that I would have done a LOT better doing this privately, without telling anybody what I was doing until somebody noticed my coins being sold, but this way seems more ethical to me.
