Diagnose and Respond to a Month-over-Month Drop in Coinbase Net Income

You are a product manager at Coinbase. The company's net income this month is 10% lower than last month's. What would you do? ```hint Split the number first Net income is revenue minus costs, plus gains or losses outside the core business. Find which of those moved, and how much the crypto market alone explains, before blaming a product change. ``` ### Clarifying Questions - Do we already know whether revenue, expenses or non-operating items such as gains and losses on crypto the company holds drove the decline, or is that for me to find out? - How did crypto prices and market-wide trading activity move over the same two months? - How large are normal month-to-month swings in net income, so I can judge whether 10% is unusual? - Am I answering for the whole company or for a product area I own? ### What a Strong Answer Covers - Confirming the number first: calendar effects, one-time items and normal volatility - Decomposing net income into revenue lines, expense lines and non-operating items, then drilling into the line that moved - Separating market-driven causes (prices, volatility, interest rates) from company-driven ones (fees, product changes, outages, spending) - Checks that confirm or rule out each hypothesis, in a sensible order - A response matched to the cause, with guardrails so short-term fixes do not hurt users or trust ### Follow-up Questions - The whole drop is explained by lower trading volume across the crypto market. Is there anything a product manager should still do? - Finance proposes raising retail trading fees to recover the shortfall. How would you evaluate that proposal? - Which metrics would you watch daily to see a decline like this coming before the month closes?
