At the moment the price of XEM is really pure speculation but that was no different from NEMstake from June 2014 to March 2015. . I think NEM's mobile client is coming out in a week or weeks (...months?) but, as awesome it could end up being, I don't think it by itself will send XEM into the stratosphere.. because there's already some alts with mobile clients and it's not really a huge wow factor.
NEM Is released and trading? I must have missed the news.
Time to claim the coins if someone can provide a link.
nem launched march 31, 2015 at 19:00 UTC. About 2 hours later Poloniex opened trading for XEM/BTC. Currently XEM is only trading on poloniex. However it's speculated that more exchanges will become available this week and weeks to come.
