Basically, a random number between 10 and 20 bitcoin would be bought every 5-10 minutes, non-stop, for at least a month on end until the end of January. Each time, (1) an account was created, (2) the account spent some very exact amount of USD to market-buy coins ($2.5m was most common), (3) a new account was created very shortly after. Repeat. In total, a staggering ~$112 million was spent to buy close to 270,000 BTC – the bulk of which was bought in November.
It needs to be recognized that, whether intentional or not (though plausible ignorance only goes so far), Mt. Gox has effectively been abusing Bitcoin to operate a Ponzi scheme for at least a year. The November “bubble” well into the $1000?s – and possibly April’s as well – was driven by hundreds of millions of dollars of fake liquidity pumped into the market out of thin air (note that this is equivalent to “with depositors’ money”). It is only natural that the Bitcoin price would deflate for around 5 months since its December peak, since there was never enough fiat coming in to support these kind of prices in the first place.
