What Is an Altcoin Exchange?
An altcoin exchange is a digital marketplace where users can buy, sell, and trade cryptocurrencies other than Bitcoin—such as Ethereum, Solana, Cardano, and thousands more. These platforms act as intermediaries, matching buyers and sellers while providing tools for price analysis, order execution, and secure storage.
While some exchanges focus solely on crypto-to-crypto trades, most top platforms today allow you to deposit fiat currency (like USD or EUR) via bank transfers, debit cards, or eWallets. Many also offer additional features such as staking, copy trading, futures contracts, and DeFi integration.
