Selecting an appropriate cryptocurrency exchange requires careful consideration of various factors. Every crypto exchange has pros and cons that must be evaluated based on individual requirements. This article reviews the top platforms suitable for crypto newcomers and experienced users in 2025.
Cryptocurrency exchanges can be categorized into several distinct types, excluding derivatives-focused platforms. These categories encompass instant cryptocurrency exchanges, retail centralized exchanges (CEXs), peer-to-peer (P2P) exchanges, and decentralized exchanges (DEXs). Based on recent years’ experience, many users prefer instant crypto exchanges and non-custodial/self-custodial platforms because they provide direct control over cryptocurrency assets.
Types of Crypto Exchanges
Instant Crypto Exchanges
Instant crypto exchanges like Changelly, SimpleSwap, and others focus on speed and simplicity for the end user, many may not be interested in endless verifications and nuances of CEXs, P2P, and DEX platforms. They often offer ease of use and swift transactions without custodial ownership of assets.
Retail Crypto Exchanges
Retail crypto exchange platforms like Binance, Bitfinex, Coinbase, and others are centralized exchange (CEX) outlets with extensive order books; however, trades are only executed according to the latest price movement of the market. They offer a lot of flexibility and features for traders. Most retail exchanges are used for crypto-fiat and crypto/crypto transactions. However, a few retail examples may also offer strictly crypto-crypto transactions. The key concern about CEXs is their custodial ownership of digital assets, which makes them vulnerable to manipulation and cyber attacks more than other types of exchanges.
P2P Exchanges
P2P exchange platforms like LocalBitcoins and Remitano are also popular, especially in regions with high fiat volatility. Users themselves create listings of how much crypto they would like to buy or sell, and interested parties can view their offers in the respective sections. However, these P2P outlets demand extensive verification and engage in complicated KYC exercises.
Decentralized Exchanges (DEXs)
Decentralized exchanges, or DEXs, like Uniswap, SushiSwap, and others allow non-custodial crypto-to-crypto exchange activity on their respective platforms. They don’t handle user funds at all and merely act as facilitators of different crypto-to-crypto trades. This gives users a chance to improve their privacy and protection against online attacks. DEXs are especially useful for privacy-focused traders who aren’t interested in fiat conversions.

- Speedy transactions. Instant crypto exchanges allow trades to be executed nearly instantly.
- Minimal verification requirements. Instant crypto exchanges are often non-custodial platforms that are much more straightforward to use because of low verification requirements
