Someone is putting those sell big sell orders to keep the price under 1000 satoshi. Who wants cheap LTCD? Well your play won't work, cuz you cannot stop LTCD going up to 1500+ levels ! You can artificially keep it under 1 K only for some time , but it won't be long buddy !!!
Those sells at 900 something satoshi will get eaten like you've never seen it before ! Get ready to see that and cry.
