What is an altcoin?
Altcoins are all cryptocurrencies other than Bitcoin. Although $BTC was the first and most established cryptocurrency, altcoins emerged to overcome its limitations and offer additional features and capabilities.
Altcoins typically serve different purposes. Some, like Solana and Litecoin, aim to improve Bitcoin’s performance by focusing on scalability and speed, while others, like Ethereum, offer innovations like smart contracts and decentralized applications.
