Not fondy of Safex Cash, though I do like Tender as suggested above.
I’d really like to see the name tie in to the ideological vision for the exchange. A true free market. Maybe a synonym or term associated with the free market (agora would have been a good name for the chain save its dark net use).
I think if you can capture the vision of the marketplace in the name, that’s great. Otherwise if you can capture the concept of a market or currency in a cool way, that will help with adoption.
Hmmm… just thinking in text. How long do we have to pitch name ideas?
