Compare platforms by how well they support you in Türkiye. Check if they offer TRY trading pairs, local payment rails, and clear support in Turkish. Review the total cost: trading, deposits, withdrawals, and network fees. Look for security tools like two-factor login, withdrawal allowlisting, and device management. Read how they store assets and handle incidents. See if verification is smooth for national ID holders. Test the app on your devices. Finally, confirm customer support hours and response times.
