Today Nem (xem) will experience a hardfork in approx 5 hours from now
Its highly recommended you back up all keys to your accounts Before the fork.
Nem is normally tight lipped about releases known as "NinjaReleases" but a event of this magnitude is a signal that something big is coming.
FORK PROGRESS HERE:src="http://chain.nem.ninja/#/search/ee58cedb95d45e80596882f0556e1bde8f43c2ae8253dadaae7d2996e3a68463"
Anyone have any idea how this will affect tokens held in exchanges such as Bittrex?
Any nem held on exchanges will be safe.
