Fake or real it doesn't really matter. Someone with 8k coins is trying to keep the price down. He's sitting there hoping to get some panic sellers. If he does he'll probably dump 1-2k also.

While he might not want to sell and he'll pull the wall, he's still trying to push the price down. Which means you take the price drop with a grain of salt. It's not the market moving down, it's someone who's pumping/dumping trying to make money. BTC market is small enough one person can push the price around pretty easily. Someone pushed the price up with bid walls twice last weekend so it works in both directions. It could very well be the same person.
