I like the Ñ symbol because It is very simple and elegant.
Short term - N
Long term - ℕ
As an Spanish speaking person, I would be really proud of having our Ñ as symbol for NANO, and I think other people would also like it.
If I press the N key on my phone I only have 2 options: Ń and Ñ.
This also could have a good impact, because Spanish speaking countries see this letter as a representation of their cultures.
I created a shortcut recently in iOS where 'nn' automatically transcribes to ⩘⩗ and I like that it slopes the same way as the NANO logo - it's unique and large enough to pick up quickly.
The short-cut is loaded to iCloud and available on all my devices - including OSX.

Not bad at all actually
I don't like ⩘⩗ really much, because it takes many spaces and doesn't align well with other symbols.
Imagine bookeeping some Nano transaction

It aligns better using a single space symbol
