I agree this is true, it turned out that this was no manipulator but a mere fool who wasn't patient or experienced enough to split his selling upon multiple markets and over time, in addition to selling into a short-term highly depressed price.
We cannot say that he was a fool. The option to spread his sale over a longer period (by multiple separate offers or by posting a higher price) carried the risk of the price falling even lower. The price may be "depressed", but may also be "still overinflated".
In any case, at this point, it seems that a more complicated and lengthy sell plan would have given him only 10% more than what he got.
He could have netted 24 M $ by selling in January, or nearly 20 M $ by selling in June. At this point, one could say that he was a fool for not doing that.
If he bought at 20$/BTC or less, he netted nearly 9 M $, with little effort and investment. He would have to be very greedy, or addicted to gambling, to feel unhappy with that result.
Let's see how his buyers will fare now.
