How can crypto be used in real world applications?

Cryptocurrency has several real-world applications beyond speculation. Bitcoin serves as a store of value and enables cross-border payments without intermediaries. Ethereum powers decentralized finance (DeFi) applications where users can lend, borrow, and trade without traditional banks. Some companies accept crypto as payment for goods and services. El Salvador adopted Bitcoin as legal tender in 2021. Blockchain technology enables smart contracts that automate agreements in supply chain management and insurance. Stablecoins like USDC provide price stability for everyday transactions. NFTs tokenize digital ownership for art and collectibles. Developing nations use crypto to access banking services without traditional infrastructure. However, adoption remains limited due to volatility, regulatory uncertainty, and technical complexity.
