1 NEM (XEM) = 0.01 $
100 NEM = 1 $
1 000 000 NEM = 10.000 $
It would be wonderful if it comes true. I don't see it going that high, but 4-5 times more than today would be nice.
It's not that unreasonable, although it probably won't reach that price for many months or even years. NXT reached a peak of about 11 cents back in June 2014 when its market cap shot past $100 million. If NEM had the same market cap as NXT did during that time then each NEM coin would be worth slightly over 1 cent. If Bitcoin and the whole crypto market undergoes another spike like it did back in November 2013 or June 2011 and NEM successfully establishes itself as one of the top 10 or 20 cryptos, then 1 NEM = $0.01 could be possible.
Another way of looking at it is; with a $650 Bitcoin price, BTC would currently have a market cap of 9 billion dollars. If NEM had 1/100 of the market cap of Bitcoin, it would have a market cap of 90 million dollars. That's about 1 cent per coin.
