Crypto Exchange
A venue for buying, selling and trading cryptocurrencies, operating either as a centralised custodial business or as on-chain smart contracts.
What Crypto Exchange means
Crypto exchanges come in two structurally different forms. A centralised exchange takes custody of client assets, runs its own order book off chain, matches trades internally and settles on its own ledger, only touching the blockchain when users deposit or withdraw. A decentralised exchange is a set of smart contracts where users trade directly from their own wallets, usually against pooled liquidity priced by an automated market maker formula, with every trade settling on chain and no one holding customer funds.
Centralised venues generally offer deeper liquidity, faster matching, fiat on and off ramps, margin and derivatives products, and a familiar interface. Decentralised venues offer self-custody, access to tokens long before any listing, and no account approval, at the cost of paying network fees on every trade, accepting price slippage set by pool depth, and exposure to smart contract failure. Many traders use both, holding working capital on a centralised venue and using on-chain venues for assets not listed elsewhere.
Counterparty risk is the defining concern with custodial exchanges, and the history is not reassuring: several large venues have failed through hacking, mismanagement or fraud, and customers became unsecured creditors. Regulation varies enormously by jurisdiction, and the client asset protections familiar from regulated brokers frequently do not apply. The standard precautions are to withdraw balances not actively being traded into self-custody, enable strong two-factor authentication, and understand which legal entity actually holds the funds.
Worked example
Swapping 50,000 USD of a mid-cap token on a decentralised exchange with only 2 million USD of pool liquidity can cost several percent in price impact, whereas the same order on a deep centralised order book might slip only a fraction of a percent.

Trade with a regulated broker
Understanding the terminology is the cheap part. The expensive part is choosing a counterparty whose execution, financing and withdrawal behaviour match what the marketing implies. Every broker below has been reviewed with a funded live account, and each review states which legal entity and which regulator applies to the account you would actually open.
