Buy orders have doubled in the last few days, but there's nothing significant for sale anywhere near the bid. As soon as a few people get wise and start raising their bids it's going to set off a chain reaction that sends the price back over 3k where it belongs. If you aren't competing for the tiny trickle of sells now you're going to be paying a lot more later... or perhaps not buying at all. That 10 BTC dump you're waiting for just isn't going to happen at this price.
