I can responsibly say that offshore crypto exchanges (like BN, OK, etc.) are unlikely to join CRS within the next five years: - Low KYC requirements, for example, you can pass with a Palau ID or a Thai driver's license - If KYC thresholds are raised or secondary KYC is required, market share will rapidly decline - Take BN as an example, which country is the exchange entity based in? Which country is your account registered under? Even cz might not know the answer to this v I offer 1-on-1 identity and tax planning guidance for 5000u.
