You want a platform that fits your needs and follows Australian rules. Check that it performs identity checks and explains how it holds client assets. Compare fees, supported coins, funding and withdrawal options, and order types you plan to use. Review security features such as two-factor sign-in, withdrawal whitelists, and cold storage practices. Test customer support and educational resources. Read the terms, especially on custody, outages, and account limits. Start small and build up comfort over time.
