Was thinking about safecoin name alternatives and the word saffron came to mind. It also fits well with a farming analogy.
Another nice artistic similarity is that the flower itself has a hexagonal shape much like the safe network logo.
So I would propose an official spelling of the word as either the generic:
SAFFRON
Or an alternate spelling :
SAFERON
With the alternative spelling we can continue to use “safe”, “safes”, “safer” or “safers” as shorthand. The market ticket symbol could be SAFE, SAFR, or SAFER.
And if you don’t like any of those, there’s always “SAFE-A-RONI”.
