Start by checking if the platform supports deposits and withdrawals in Mexican pesos. Review the full fee schedule, including trading, conversion, and network costs. Look for security features such as cold storage, multi-factor authentication, and withdrawal controls. Check available payment methods, limits, and support hours in Spanish. Read the terms, especially on custody, outages, and dispute handling. Compare the user interface, reporting tools, and learning resources. Make sure you understand identity checks and what data is collected. Do your own research and confirm the platform complies with local rules.
