什么是数字货币？

数字货币是一种基于加密技术的虚拟货币，它使用密码学算法来安全地管理和交易资金。与传统的法定货币不同，数字货币不依赖于中央银行来发行和管控，而是依靠去中心化的技术共识算法来验证和记录交易。数字货币的发展源于比特币的推出，后来涌现出了众多其他类型的数字货币。

What is cryptocurrency?

Cryptocurrency is a type of virtual currency that is based on cryptographic technology. It uses cryptographic algorithms to securely manage and transact funds. Unlike traditional fiat currencies, cryptocurrencies do not rely on central banks for issuance and control. Instead, they rely on decentralized consensus algorithms to verify and record transactions. The development of cryptocurrencies originated from the introduction of Bitcoin, and later, many other types of cryptocurrencies emerged.
