If I understood your question correctly.
That really depends on people. If they find it easy to understand, they will agree on a standard… in this case (GB) is a likely choice. But I can’t say for certain what they will prefer.
Just to clarify, SAFE GB is the currency, Safecoin is like the commodity/stock/futures.
So it would be like this…
Safecoin >> SAFE GB
Barrels >> $USD
I realize this is very strange. But instead of the Banks printing fiat, SAFE Farmers are generating SAFE GB, limited by real consumable resources.
