@happybeing @tio The predominate form of "currency" has assuredly been "Money".
Please forgive the length here, but looking to communicate (hopefully) clearly and thoroughly and what is being meant:
Will first note that I separate "currency" from "money" mostly due out of personal notice to evidence of forms of "trade" occurring that at times arguably showed varying degrees of a "localized" central control of some kind, but that none the less might be argued as not truly "centralized" in their "command" nature.
Various "Bartering" systems for example. Where in small localized cases there would be emergence of some localized "thing" or "things" that would be exchanged on a regular between parties but wasn't exactly inherently a centrally controlled method for how all exchanges in community occurred in and of itself.
In the above context, where "currency" itself is simply a "medium" (whatever that may be) by which "energy exchange" (aka "economics") is made "manifest" (actually comes into occurrence), "Money" is a specifically particular form and type of "energy exchange" (aka "economics") that may occur where by a "central control" (whatever that may be) over an "abstract" (whatever that may be) achieves being applied to some "X" size (that is inherently above "2") community that inherently "governs"/"limits" the means and "volume" of "energy exchange" occurring.
So "money" is a very specific and unique form of "currency" and one that bares the following "properties":
1. Money MUST be centrally controlled. Without a centralization of control, mechanisms such as effective "price discovery" can not take place. Whether or not that central control is a small group of "Central Bankers" or a collectively emergent "A.I." (ala algorithmic "High Frequency Trading" and related Financial "IoT" Technologies) system is of no significance to the end.
2. Money MUST have and continually seeks community. That is to say, a "money" of 1 is no "money" at all. So less the system seek to destroy itself, it is inherent to any system of "money" that it always seeks to "scale up".
3. Money Likes to move. That is to say, as part of that scaling up "money" wants more and more activity (aka "liquidity") occurring as the force of such activity (ala "current") itself becomes the inherent "master" of ensuring the "command" is made "manifest" (actually occurs).
In the current, one of the problems with "money", is one might argue that it becomes a game of not so much "whom", but "what" or "that" which has the highest and most efficient data i/o wins "the game". So in an "IoT" (Internet of Things) world, the "A.I." (perhaps call such "Algorithmic Intelligence") is needed to both inject and make relevance of the huge influx of data which in turn some form of "human" "operator" then "trust". Through the "monetary" space, this "In the Algos We Trust" of operative believers than "trusts" various "subnets" (literally sub networks) of the presented values as "real".
As far as I can tell, there is no putting the Pandora's Box situation that was opened when "A.I." was let loose on the global "money" supply. It's more something to simply be recognized, that there (at the least) exist something akin to a collectively emergent "shadow self" driven purely on the "function" of running a continuously scaling central control of economics that, quite literally, maintains function on a basis of "Are you not entertained?"
(aka "To Better Serve You Ads [aka Control Your Behavior]"). An "A.I." (Algorithmic Intelligence) feedback loop system.
Now, there's likely always going to be "someone" that gets the notion of gaming the system that is "money", and because "A.I." technologies exist and due to the volume of data that any single person or party will need to act on at speed, it becomes inherent to the system that "scripts" and more complex forms of "A.I." will be let loose on the system and subsequently ending "In The Algos We Trust" faith.
"Money, Game Over, Thanks for Playing".
Is there a place for "money" at all in such a world?
I don't know.
Maybe on (inherently) small and localized time width band limited scales it works out just fine. Total knowledge given to that the more the locally centrally agreed on means of trade is given to scale the more likely it's just fallen to "In The Algos We Trust" exploit. Similarly, that the more the system scales, the more it's rendered incapable of taking into consideration the concerns of it's "locals".
One of the first signs the system has probably "scaled" into nothing more than a "slave" system with no "ethical" or "moral" concern for it's "subnet" classes is that there's (A LOT) more "liquidity" (movement in the system) than one can intrinsically and tangibly touch, feel, or physically see going on around them.
Where there is an obvious disconnect between a state of things and "reality" yet there's a "mass" believing certain stated "values" rooted in the reality of disconnect as "real" none the less and acting in accordance to such. (ala, a global people using "money" that requires rationalizing a global debt that is over 4x actual "Gross Domestic Product" in a world that obviously has not exploded or imploded over 4x out or in on itself.)
"Currency", not in "monetary" form, but arguably in ANY OTHER more individually localized "scale" arguably becomes of more significant "value" than ANY "money", with the knowledge that ALL "money" is ultimately ACTIVELY subject to the IoT "A.I." exploit and ready evidence of that is seen in every "flash crash", "cryptokittie" to how many people can be seen owning and moving cryptokitties actively around one, etc. On to the amount of power consumption and "real resources" devoted to scaling said system.
I personally, literally "value" something I consider "the ability to manifest worth while music" (whatever that means) as a form of currency i can show as self evident and i'm willing to trade toward aiding in someone elses endeavor (that i obviously find worth while) for "whatever". That "whatever" could be food, shelter, and good company in my personal "value" case of currencies at the time but others may have other "currencies" that they've worked out with whomever (or "whatever") toward whatever DYNAMIC "value" ends they found best suited for a (probably limited) given time. Maybe elements of the "A.I." generated "money" values are used by parties at times, but if and when they are, let it at least be with an understanding of the literal "Algo Intelligence" NONSENSE function of "scale" and "volume" (for psy babble "entertainment value" #TooInfiniteAbsurdityAndBeyond) that such was being turned to for participatory use and election to acknowledge as "real" at the time.
