If there is a lesson for NEM in this NXT hack, that do not let a single exchange monopolize NEM trading volume.
I have to agree with this statement.
It's very important NEM gets on as many exchanges as possible in it's infancy to prevent exchanges from potentially causing it harm through negligence or maliciousness.
Ideally, i'd like to see NEM on at least 2 or 3 popular, reputable exchanges on release.
