Again, you can't read so, I won't waste any more time here. Any questions just read what I already wrote. Those "currencies" you are referring to are not currencies, they would be called money. Anything that can be used non-consumptively as a trade settlement is money. In no case was there a currency that WAS a final settlement. Gold coins for instance are not currency, they are literally a monetary asset. Physical USD is a fiat asset. Assets ARE the backing. Digital USD is not an asset it is a coupon redeemable for the asset (physical dollars). You can try to insult all you want, you are wrong and might be the dumbest entity I've had the misfortune of responding to.
