We can directly notice this property. Fiat currency (Dollar, Yen, Pound & etc) can be viewed and kept physically, while the crypto currency is all digital or it can be called virtual money. It's all done with our phone or computer. While fiat money is tangible and there are costs in production - the pennies and dimmers cost more than one ear to produce an ear and it is not very effective for us to continue producing these coins.
The money we hold in our pockets and in the banks is issued by the government and controlled by it and the banking system, while with cryptocurrency - it's decentralized. It is not owned or created by a banking system or by a government. No one owns cryptocurrency, and this is accessible to everyone. We control our own crypto coins and no other intermediary involved.
It's about inflation vs deflation. The value of fiat money is deflated as time goes by. A few decades ago, when we go to the shopping or grocery store, our cart is full of goods, but today given the same amount, we can not even fill the basket of groceries. The price of goods grew rapidly, while the value of FIAT money deflates. Unlike cryptocurrency, its value keeps rising day by day.
Cryptocurrency is the next evolution of banking. We are in the perfect place at the perfect time when there is technology for moving money around right away. It's more efficient, faster and more secure. There is an accounting system that is truly integrated into the economy's design and how the money goes. There are many benefits for people and businesses to adopt crypto currency.
