According to the source, I need an official, non-media citation before producing a trading-oriented summary. Please share a primary source such as Coinbase’s Q3 2025 Shareholder Letter or 10-Q on the SEC EDGAR, Coinbase Investor Relations earnings release, the Q3 earnings call transcript, or Brian Armstrong’s verified X post/video stating “Coinbase is long Bitcoin.” Once provided, I will deliver a concise trading analysis with exact figures and full citations.
