Cryptocurrency and NFTs are two digital assets that have gained significant attention in recent years. 

**Cryptocurrency** is a type of digital currency that uses blockchain technology to operate without a central authority, such as a bank. Popular cryptocurrencies include **Bitcoin** and **Ethereum**. Transactions are decentralized and secure, allowing users to trade assets quickly and across borders. Cryptocurrencies are commonly used for investment, online purchases, and more recently, as a means of supporting decentralized finance (DeFi).

**NFTs (Non-Fungible Tokens)** are unique digital assets, also powered by blockchain. Unlike cryptocurrencies, which are fungible and interchangeable, NFTs represent ownership of a one-of-a-kind item, such as digital art, music, or collectibles. Each NFT has a unique code, ensuring its individuality and value as a collectible or investment.

Both cryptocurrencies and NFTs are reshaping finance and digital ownership, but they require thorough research due to their volatility and evolving regulations.
