I've been speaking with one of the other botters now, we randomly bumped into each other on c-cex chat...
It seems he likely triggered the big sell-off last night. It looked to him like the network was having problem, and at the same time the buy side of the book was thinning, so he did the perfectly rational thing and sold the lot. Woops, the network *wasn't* having any problems, and the buy side showed resiliency and refilled the books quickly (despite leaving an epic spread over an order of magnitude large) albeit at a large discount bid.
The index error seems to be a side-effect of some weird blocks, and is annoying but benign. The fork rate of the network today is actually *much* lower than yesterday so far, probably because all 3-4 of us botters seem to have backed off slightly since being "discovered" and coming to the realization that we could quickly compete ourselves out of a market to sell to.....
(I'd like to set up something like a mining pool for the botters so that we can compete without risking such extreme chain forks. Yesterday's huge forks were painful for everyone.)
I think that since there wasn't actually some fundamental trigger for the selloff that bidding competition should cause the price to gradually recover. I would take the fact that the sell side is not racing to the bottom as a very good sign. In other words, I personally think this might be a rare, great buying opportunity! (In fact, I have now bought back over half as many coins as I've sold over the past days, heh.) Also, I would expect that if/when this coin launches on a second exchange the price would rebound almost instantly.
