If it was a scam, then how is that coin listed in Bittrex? because of reasons, the people are reducing the investment in this case, if the NXT has been 20000 Satish, and see present price... would you call NXT a scam? You need to know when you have to buy and sell.. you bought coins for a lot of price, you also need to understand that If you want profit you have to take loss.
you are right, it is stable thats why not pumping, so my suggestion if you bought then keep holding untill recover the market.
