What Is a Cryptocurrency Exchange?
A cryptocurrency exchange is an online trading platform enabling users to buy, sell, and trade digital assets like Bitcoin, Ethereum, and altcoins. Functioning similarly to traditional stock exchanges, these platforms offer trading pairs for crypto-to-crypto or crypto-to-fiat transactions (e.g., USD, EUR, PLN).
Key Features:
- Trading: Users place buy/sell orders.
- Storage: Integrated digital wallets for asset custody.
- Security: Two-factor authentication (2FA), encryption, and cold storage.
- Market Analysis: Real-time charts, indicators, and price tracking tools.
- Support: Dedicated technical assistance for platform issues.
Exchanges operate as either centralized (CEXs, managed by a third party) or decentralized (DEXs, peer-to-peer trading without intermediaries).
