P2P vs centralized vs decentralized exchanges
Three ways to trade crypto, three different trade-offs. This guide compares who holds your coins, how prices are set, what verification to expect and where things go wrong.
Comparison
At a glance
| P2P platform | Centralized exchange (CEX) | Decentralized exchange (DEX) | |
|---|---|---|---|
| Who you trade with | Another user | The exchange's order book | A smart contract or liquidity pool |
| Who holds your crypto | Platform escrow during the trade | The exchange | You, in your own wallet |
| Fiat on and off ramps | Many local methods, set by the advertiser | Bank, card and a few local methods | Usually none; needs crypto already |
| KYC | Usually required by the platform | Usually required | Usually none at the protocol level |
| Price | Set by advertisers, often a premium | Market price from the order book | Set by the pool; slippage on large orders |
| Main risks | Counterparty fraud, reversed payments | Exchange failure, account freezes | Smart contract bugs, wrong addresses, scam tokens |
Choosing
Which fits you
You want local payment methods
P2P is built for this. Accept a price premium and take the safety steps seriously.
You want the simplest, fastest route
A regulated centralized exchange gives a market price and a familiar interface, with custody risk and KYC.
You hold crypto and want control
A DEX lets you keep custody, but you carry the responsibility for addresses, approvals and token checks.
Custody
Custody is the key difference
With a centralized exchange your balance is an entry in the exchange's books: convenient, but if the exchange fails or freezes your account, you wait. A DEX leaves the coins in your wallet, but a mistaken approval can drain them. A P2P platform sits in between: custody only during the trade.
Whichever route you use, withdraw long-term holdings to a wallet you control, and keep the recovery phrase offline.
