How trades are executed
Some centralized exchanges use an order book that matches buy and sell orders. Other services use different execution models. Understanding the mechanism helps you read spreads, liquidity and execution prices.
The cost is more than the headline fee
Spread, currency conversion, deposits, withdrawals and order type can all affect the total cost. Compare the cost of a realistic transaction rather than looking at one number in isolation.
Custody and counterparty risk
On a centralized platform, part of the custody process may be delegated to the operator. That can make day-to-day use easier but also creates counterparty and access risk.
How to compare exchanges
Country availability, fiat support, fees, app quality, supported assets, deposits and withdrawals, security and trading tools are more useful than a universal ranking.
FAQ
