Many would think bitcoin dying would be the death of crypto, imo i think it's not true at all, problem with bitcoin is it's a fat ass crypto stuck in stone for many years with zero innovation during that plenty of time.
NXT/NEM platform are built to be innovative and adaptable so they can last in time and match new needs/demands.
Also, while nem can be first seen as the silver of nxt, looking at how the project is moving, i think it can be much more than that.
I feel many cryptos are reinventing the wheel or are a scam. Anonymity does have its place, but I think there needs to be a clear winner in the race to be the anon crypto. NXT has the asset exchange which I think was a huge innovation. I am not 100% confident in NEM yet, and in fact it reminds me of SYS quite a bit which worries me in the back of my mind seeing how SYS played out. But it seems to be the only coin that is promising anything real at this point. We shall see soon enough!
