🌐 What Are Altcoins?

Altcoins are any cryptocurrencies that are not Bitcoin. Many of them offer faster transactions, lower fees, and innovative use cases such as decentralized finance (DeFi), NFTs, and blockchain scalability. In 2025, altcoins are attracting both investors and developers seeking new opportunities beyond the Bitcoin–Ethereum ecosystem.
