Well one of alleviation is to try to deal locally. Like the Chinese people exchanging BTCs in their locals. If we could somehow use localbitcoins.com with no limit or arbitration/espionage then BTC would flourish more. \
Somehow it's just hard to move 1BTC or higher in local setting. So maybe do it in small and daily chunks? Well I don't know.
Just a thought on exchanges, they could be doing some maneuver but they cannot grab all the BTCs. It would be foolish to buy the majority of the coins and not move it. Somehow this reminds me of a movie "The taking of Pelham 123" They seized a train in the subway and made the stock market and $ plunge with the scenario they made. And it was shown in the latter part of the movie that the perpetrator had owned Gold shares and thus very happy of the outcome.
Just a random rumbling.
