Altcoins, short for “alternative coins,” refer to all cryptocurrencies that are not Bitcoin. These digital assets serve various purposes, from smart contracts and decentralized finance (DeFi) to privacy transactions and supply chain management.

Unlike Bitcoin, which mainly functions as a store of value, many altcoins introduce innovative features and blockchain use cases. Some altcoins, like Ethereum, enable decentralized applications (dApps), while others, like Chainlink, facilitate smart contract integrations with real-world data.

Additionally, many investors are drawn to staking cryptocurrencies, where they can earn passive income by locking up their tokens to support network security and operations.

Understanding how altcoins work and their real-world applications is crucial for making informed investment decisions. But with thousands of altcoins available, how do you choose the right ones? Let’s explore the key factors to consider before investing.
