Who's theory is this? It makes no sense, with due respect!
I have no idea whether this is correct. That's why I wrote "WARNING: PURE SPECULATION."
The bottom line is that there's no way MtGox didn't notice a slow theft of 750,000 BTC. My three contending theories in current order of preference are:
#1. What I posted above.
#2. The 750,000 BTC figure is FUD designed to buy-out GoxBTC for cheap and close the (smaller) solvency gap.
#3. The "Mark messed-up the private key to deep cold storage" theory.
R U saying that the price of BTC should bounce because 750 k are gone?...
If there are 750k BTC less than what everyone thought, I'd say that was very bullish, at least over the medium and long term.
Theory #2 is wrong because if that was the case they would not have stopped the trading engine. You can't get your bitcoins to the bitbuilder gox address without the trading engine so that would have severely limited things.
I thought they might have had a few thousand coins stolen but this magnitude of a situation surprised me.
