The NEM price on the NXT asset exchange is extremely low.
NXT price is: 0.0000898 BTC/NXT supply @ 1 billion
NEM price should be 0.0000224 BTC/NEM , NEM supply @ 4 billion
NEM price is actually 1,000,000 for 17,500 NXT = 1,000,000 for 1.5715 BTC = 0.0000015715 BTC/NEM
so that's pretty attractive. People buying at these low prices will easily make 10X - 20X their investment once NEM launches.
You are assuming that NEM should be worth the same as NXT right now. On what basis?
For some magical reason people seem to have the wildest predictions for the "NEM price after launch"
