Coinbase reports ~30 million users in 103 countries and sees ~10% of ATO attempts as targeted ATO; credential-stuffing yields ~2.5% validated pairs so defenses feed fake success rates back to degrade seller reputations. Practical controls that work include device verification requiring an email click from the same IP, injected 48‑hour cooling‑off delays, KYC selfie rechecks for account recovery, phone‑port/sim‑swap feeds, and nudges that raise SMS→TOTP conversion to ~10%. Adoption of physical tokens is currently ~1% but u2f works.
