What is a digital currency? Easy to understand explanation

You can think of digital currency as a special "game currency".

For example, if you earn gold coins you get by fighting monsters in a certain game, these gold coins can only be used in this game. Digital currencies, such as the most famous Bitcoin, are like "super game coins" that can be recognized and used by many people around the world. Its value is not determined by the game company, but by everyone who believes in it and uses it, so the price will fluctuate continuously.

It has several key features

Decentralization: There is no "headquarters" or "central banks" in digital currencies. It runs on a technology called "blockchain". This technology is like a public "public ledger" distributed on countless computers around the world. Every transaction will be recorded in this ledger and can be seen by everyone, but no single person or institution can easily tamper with it, which is very safe and transparent.

Global Common: As long as there is a network, you can send your digital currency to another person in any corner of the world, which is usually faster and has lower handling fees than banks cross-border remittances.

Anonymity and Transparency: Transactions are publicly recorded on a "public ledger", but your identity information is usually represented by a string of codes (account address), which provides a certain degree of anonymity.
