NEM/XEM is a good coin for longterm holding. Should be accumulated at area around 50cents (25%-33% of planned money to invest), 20-30cents area (25-33%) and at around 10cents (50-33% of planned money to throw in). Problems with recent coinchecks hack, and generated from other exchanges (having like bittrex problems with going online with deposits, they are so lazy to change their wallet to multisignature and introduce mechanism to not receive stolen XEMs) giving a good chances to get XEMs so cheap as possible. First goals after accumulation phase (i think this phase should be to april-june 2018) is target around 4$ or little higher. In wider longterm period (1st Q of 2019) the goal for XEMs quoting in USD is around 60$ (no it's not typing mistake 60 american dollars!). See You in the future, dont forget to buy this tickets, before another one ride to the stars;)
