Coinbase has significantly reduced account restrictions by over 80% as part of its efforts to balance user security and accessibility. This move follows improvements in the platform's fraud detection models, which have been optimized by approximately 20% in recent weeks. The enhancements include infrastructure upgrades to enable continuous retraining of multiple models, aiming to protect users from unauthorized access while minimizing disruptions. Coinbase's head of product, Dor, highlighted a recent fraud case where a transaction was suspended to verify its legitimacy, leading to temporary account restrictions. Although this measure is intended to safeguard users, it resulted in frustration for a legitimate user who had to undergo the account recovery process. CEO Brian Armstrong emphasized the importance of reducing account limitations while maintaining robust security measures, underscoring the platform's commitment to finding the right balance between user protection and convenience.
