KuCoin provides a professional, secure, and convenient crypto exchange service with low fees. Testing KuCoin revealed UI and localization defects. They are no showstoppers and don't affect the app's functionality but create obstacles on the user journey. More emphasis should be placed on regression testing to reduce the number of similar bugs.
