I really think this is just a manipulation strategy and a solid FUD by most people that want the price to really go down, there is a possibility because the market is really volatile and unpredictable but the $800 price is really very low for a speculation in my analysis the price of BTC can still go down to $2000 USD and will be not any further go down from that value, I guess they really want to set an uproar to some weak hands so they would sell their bitcoin and they can buy cheap.
