Indeed. There had been reports that someone moved their 11 thousand bitcoins from the wallet so that they can start trading of it. And highly doubt that this is the guy who's dumping the bitcoin like crazy and shook the world right now. The net effect followed by panic sellers as always where they started to dump the crypto currencies and thus total market cap is disturbed one more time here. Overall it is dropping currently and keep doing so until the time comes when all the seller walls will be filled up and then buy walls will be taking over. Just imagine those 11 K BTC are currently worth equal to 11,000 X 7210 (price at the time of first dump occurred) = 79310000 USD !! Thats huge dump!
