Do you mean electronically circulating ?
Answer depends if I understood you or not :) :
(If not, probably barrier language, I do not get what you mean if it's the case.)
(If yes, speaking about gold, I prefer physically than electronically).

I don't consider the Gold Backs to be a Currency... I would say they're more of a Work of Art, using a Set amount of Gold... They are Collector items for sure, and may very well increase in Value... U.S. Electronic Coinage, as per my "Fine Tuned" version of the coming Monetary Correction, will be 100% backed by "U.S. Gold Coins"... One ounce of Gold will get me $90 in U.S. Electronic Coinage or $90 in U.S. Gold Coins... They will be in Perfect Balance with each other... One will get you an equal "Face Value" amount of the other...
As long as they are really baked by gold ... Remember what bankers did, they broke tthe gold /crrency value link... On purpose.
Thnak you for the complement in information.
