AMP is a huge buy right now. Wildspark.me is already awesome by itself and no one really knows how product X is going to function with it. It could blow everyone's mind. Now is the time to buy not sell.
Because something is low that doesn't mean it can't go any lower. I am not saying you can't make money by shortterm trading it. But to buy and hold it ... it is not worth the risk. All coins are cheap now and many have a much better value proposition than AMP.
