"Bit Gold" usually refers to Bitcoin (BTC). It was proposed by Satoshi Nakamoto in 2008 and officially launched in 2009. Bitcoin is a decentralized digital currency with a limited supply of 21 million. Its issuance and transactions rely on the internet, and it serves as a store of value. It is often considered "digital gold" and holds a groundbreaking and benchmark position in the digital currency field. "Lite Silver" refers to Litecoin (LTC). This is a digital currency inspired by and improved upon Bitcoin. It was designed and implemented by Charlie Lee, formerly of Google, and officially launched on November 9, 2011. While technically similar to Bitcoin, Litecoin also has its own unique features, such as its use of the scrypt algorithm, which allows for faster transaction confirmation times, greater network transaction capacity and efficiency, and a maximum supply of 84 million, four times that of Bitcoin. The phrase "Bit Gold, Litecoin Silver" vividly depicts the relationship between Bitcoin and Litecoin, both of which hold important positions in the digital currency market.
