it has been happening on many coins on bittrex. bots create sell orders at low. mostly of no more than 0.01btc, they create a range of 200 satoshi with such little value. The coin seller thinks price is going and sells at whatever price the "bot" is buying. Then bot sells it with +50 satoshis to next buyer and creates ridiculous sell orders again until the next victim.

So you all should relax and hold the coins. Like we all are holding. Like I have bought at 1200. Others have bought at 2000.
