Yes it's impossible to sell, because you can't put a sell order  under an index price. But the DEV can do it! So he always sell his coins and your sell orders get canceled . for example: the index price is 140. your sell order must be over 140 $ . The dev can put a sell order below 140$ for example 128. So, when someone buys sumcoin, he buys at 128,and your order get canceled.   DEV uses a BOT for this joke. In fact the price goes down slowly during the day,  then a big up , and slowly down... repeatedly. See the graph!  FAKE COIN. ONLY DEV  can gain in the exchange. SCAM!!!
