About virtual currency, there are 03 different understandings:
Money is unmanageable, no physical shape and is used in electronic environments, it is called virtual money.
The type is not real value, not guaranteed by cash, gold, and valuable assets.
The money is usually used to pay for games in electronic games, each type of game has a different currency and they can not be used to exchange for each other or to bring out the electronic environment to buy. Other service products are.
The concept of virtual money is born, widely used and most often by the third interpretation itself. With this kind of money, the balance can be managed and easily changed by the issuer without affecting the financial or market economy.
I feel like virtual money is significantly different from crypto currency. Mainly, crypto is usually anoymous and decentralized.
Virtual money, for me, refers to just any form of payments that's done online. I think venmo and PayPal are modes of operating virtual money, so as you can tell, in my definitions, it's pretty clear what the differences are.
In this sense, virtual money has been around for a while, and crypto currency is just a piece of that virtual money pie.
