Coinbase Product Manager: Account limits have been reduced by 80%, and fraud models have been improved by about 20%

Mars Finance News: Coinbase's Product Head Dor posted on X platform that this week, they handled a fraud case. After choosing to suspend trading and request more information from the user about the transaction, they decided to reject the transaction and restrict the account due to inability to contact the account owner, with the aim of preventing account misuse and protecting users from unauthorized account access and withdrawals. However, this led to a frustrating user experience for a legitimate user (who must go through an account recovery process). Coinbase is balancing this situation, having already reduced account restrictions by over 80%, optimized fraud models by approximately 20% in recent weeks, and upgraded infrastructure to continuously retrain multiple models. Coinbase CEO Brain Armstrong responded that it is crucial for the platform to both reduce account restrictions and ensure customer safety, finding an appropriate balance.
