You are assuming that people in general are pushing this down, your wrong. It was a flash crash on bitfinex.com caused by deliberate manipulation, absolutely nothing to do with public sentiment or news.
Manipulation? It's disheartening to learn someone can hack into the exchanges and sell all the bitcoins, thats what I call bad sentiment!
thats not what market manipulation is...someone with a lot of coins sold them to trick the bots, no one hacked an exchange and sold other peoples coins..
This. And I think now that people can profit both ways (long or short) manipulation is simply a given, both on the exchanges and on the forum. More arguments will appear in favour of bitcoins downfall, for profits sake. Is that good? Im not so sure. The sad thing the USD is more reliable atm as i dont see some russian nerd coming on to forex and knocking the usd down 8 % in a flash.
