Ever wonder what happens to your Bitcoin transaction after you hit send? In this episode,  Kenshin and McIntosh dive deep into the mysterious world of the mempool — the holding area for unconfirmed Bitcoin transactions. You'll learn why transactions get delayed, dropped, or stuck, and how to avoid overpaying on fees with tools like RBF (Replace-by-Fee) and CPFP (Child Pays for Parent).
