Apparently https://www.overstock.com/ is now accepting a lot of altcoins (http://fortune.com/2017/08/08/overstock-digital-currency). It’s great to see NEM’s logo before LTC :D. I really hope this trend continues…
It says they use shapeshift, does that mean that shapeshift will support NEM? I don’t see it in the list at https://shapeshift.io/#/coins
