Well I have sold most of mine already before it hit this price. The price just continues to drop, and the devs do not have any real pr. This reminds me of caix coin a few years ago. The dev just disappeard for months and the price slowly went to nothing. Most people I have asked what exactly does ardor do have no clue what it does because even the devs can not explain it in simple terms. Most people on the poloniex troll box seem to think you have to have ardor and nxt to get Ignis, but you only need nxt. So as far as whether you should sale or not is up to you if you want to wait untill next year when Ignis is about to come out and the price will rise again. Their is just no tell how much it will.
