#cryptocurrency. until the emergence of cryptocurrency, many people failed to understand the true concept of fiat currency.
I got into an argument with a friend who said crypto is too digital to be a currency. I had to then let him know the fiat money is backed by nothing like gold either; rather, it is a designed paper, agreed upon to serve as a legal tender.
I further took him back to history to brief him on the transformation money has undergone, which qualifies crypto to be a legal tender.
Should you encounter someone too, too stubborn to accept the fact that crypto is money, explain to him or her what changes happened to money first, and crypto is part of that change.
