See:
Report: Mt Gox Data Provides More Clues to Trading Bot 'Willy'http://www.coindesk.com/report-mt-gox-data-provides-more-clues-to-trading-bot-willyIt's mostly a rehash of the
Willy Report, but this seemed new to me:
More information is also needed with regards to what happened to the bitcoins bought by Willy, as well as the USD that "reverse Willy" [emphasis added] had accumulated in February.
Willy's purpose is also unclear. More clarity is needed to decipher whether it was simply a buying tool or whether it attempted to manipulate the market price.
I've never heard anything before about a "reverse Willy". If there was any short selling going on with all of the coins purchased by Willy and Markus, perhaps "reverse Willy" was involved in unloading them. Anyone know anything about this
reverse bot?
Mt Gox was in the hole cashwise by the end of February, so what happened to all the USD supposedly accumulated by "reverse Willy"? Follow the money!
The report explains it: Willy, or a robot that behaved very much like it, started selling BTC instead of buying BTC, apparently after the price crashed.
In my theory, that would be expected: Willy was doing arbitrage between MtGOX and some Chinese exchange, and the Chinese exchanges were leading the price. Then willy should buy while the price was rising (because the price in China would be higher than at MtGOX) and sell while the price was crashing (when China was lower).
My guess is that, during the rally, Willy had been buying real BTC with non-existing USD. The owner hoped to get the CNY out for China at a later time, and fill the USD hole in MtGOX's accounting (with profit) before anyone noticed. Later, during the crash, the reversed Willy would have been selling non-existent BTC (since the real ones had been already sold in China) for USD in the client accounts. Although these were mostly nonexistent USD, the trades still made sense because they reduced the size of the USD hole that Willy's owner would have to fill, whicle creating a BTC hole of a somewhat smaller value (because of the China-MtGOX spread).
But (still my guess) the CNY were not taken out of China, either intentionally or due to some snag (the PBoC decrees, default by the Chinese accomplice, whatever). So MtGOX was left with huge BTC and USD holes, an the rest is history.
Beware about putting too much weight on the "Willy report" by that investigative firm. It is entirely based on the leaked database, which was copied by parties unknown sometime before the final collapse. We do not know whether the leaked copy is reliable; it may have been doctored and leaked specifically to shift the attention away from the real facts and culprits. Indeed, we now know that the copy that the police got from the servers was incomplete (or worse). The leaked database included records of deposits and withdrawals, but the firm has no way of checking whether those records match the actual deposits and withdrawals. In particular, AFAIK the blockchain addresses that received the BTC widthrawals were not leaked. (The police has bank records, and should have those addresses, hopefully.)
