Falling from 80 cents to 5 cents isn't "almost the same" regardless of how you spin it.
It fucking crashed. Not that the underlying tech isn't great and there isn't tremendous room for growth, it is, and there is. However, NEM, like most coins, was way too high one year ago, and came crashing down with every single other coin.
Suddenly today crashed even more!
What to do now? Panic buy or panic sell?!

Well, let's admit it: competition in the crypto space is brutal. Without any real catalysts to encourage broad speculation in the marketplace, NEM (like anything else) will have to depend on increases in real-world adoption to gain any positive traction. However, if and when another strong bull market manifests itself, then it will likely be one of the prime recipients of a capital injection.
Basically I don't know and your guess is as good as anybody's.
