first of all: congratz man!
this shape is very well thought through & logical.
nor to symmetric neither to asymmetric.

and guys please..
good logos are always an abstraction.
its not possible to grant PERFECT readability (If you work with letters at all) and at the same time have a logo with an incisive shape you actually REMEMBER. right?

In other words you cannot have the cake and eat it.
And imo the Abstraction/Readability-ratio is pretty much as good as it gets. (And ive tried a while myself)
In my Impression most people, including myself, read NEM and not something else.
Once you read "NGI" it of course sticks with you.

But just think of the NXT-logo for example^^
You could read almost anything into it (eg. XXT), and people are still fine.
Because its a good logo, that people REMEMBER.
Logo critic should be balanced and not overlook this context.
