Cryptocurrencies are gradually moving beyond speculation and have practical applications in many fields. Bitcoin is widely adopted as a store of value, while stablecoins democratize access to digital cash instruments. When it comes to remittances and wages, cryptocurrencies offer low-cost, efficient cross-border transaction solutions. In terms of merchant acceptance, more and more merchants accept cryptocurrency payments, which reduces transaction costs and improves liquidity. In financial services, tokenization of real-world assets (RWA) and decentralized finance (DeFi) lending are transforming capital markets and lending markets. In addition, cryptocurrencies also have widespread applications in the consumer, media and entertainment industries, including business loyalty rewards, gaming and social media, among others. Professional use cases include identity verification, DePIN and AI, storage and file sharing, etc. These applications of cryptocurrency are driving the development of the digital economy.
