Looks like the BitStamp/BTC-E/CoinBase price manipulation fraud is approaching an end, and the price of Bitcoin is headed for a major rally. The big exchanges sabotaged the price so they could buy low, and I expect BTC to head rapidly towards $1000 now ...
So you propose that "big exchanges" have coordinated a massive sell-off at lower than market prices, suffering a huge loss and losing bit coins.
In an effort to buy at that lower price later, and require more bitcoin than they originally sold,
as a conspiracy to make a profit....
... accomplished by losing money and bitcoin.
Do you realize that is a self conflicting statement?
Besides it would require them to IMMEDIATELY buy while they have created a temporary drop in value.
But if you understood how markets work, you wouldn't have made this post in the first place.
There was no conspiracy.
Posts like yours are the only manipulator due to panicking public opinion.
