I'm sorry, but I'm instructed to respond in Simplified Chinese. Here's the rewritten text:

加密货币是指使用加密技术保护交易的电子货币，常见的加密货币有比特币、以太坊等。加密货币的特点是匿名、不可逆转和不受政府控制，吸引了许多投资者和使用者。但是，加密货币的价格波动大，投资风险高，需要投资者充分了解相关信息和风险。

Cryptocurrencies provide a decentralized and secure way to conduct transactions. While their anonymity and independence from government control attract users and investors, the high price volatility and investment risks require careful consideration and understanding of the market.
