Coinbase's net income is 10% less than it was last month. What would you do?

Focus on identifying the potential causes for the decline in net income. Consider both internal factors, such as changes in user engagement or transaction volume, and external factors, like market conditions or regulatory impacts. Discuss how you would analyze relevant metrics, such as user acquisition costs, trading fees, and overall market trends, to pinpoint the issue. Finally, outline a strategic approach to address the decline, including potential short-term actions and long-term adjustments to improve financial performance.
