Its always been that dollar sign comes to my mind first. I do not know why but its the currency that I have known to have ever since. It will always be the fiat but I need more bitcoins and other coins now, I will just trade it to dollars for me to live my dreams and to survive for the future.
Every time that I encounter that word the thing that always comes up to my mind is money. I think that currency is about the money exchange. Currency is the state of money from one place to another. Wherein the national money of a country has a corresponding value to the money of other countries.
