The original movement Mt. Gox funds are thought to have kicked off the bear market starting in January of this year. But this time its different; institutions are coming to the crypto markets, and how these markets will react to this new movement of funds remains to be seen.[/i]
No. Movement of bitcoin from a wallet address known to be owned by Mt Gox would not cause a bear market. The funds were only moved from one bitcoin wallet to another bitcoin wallet - that's not a sale, that's a transfer. A bear market could only be caused by one transaction if that transaction was to sell Bitcoin for a fiat (or any other) currency.
This is how supply and demand works.
