It's been 15 years since Satoshi Nakamoto stepped away. His final post marked the end of an era—the original Bitcoin creator logged off and never returned. That moment remains one of crypto's most iconic milestones. Whether it was intentional withdrawal or simply moving on, Nakamoto's departure left the protocol to speak for itself. A decade and a half later, his creation continues reshaping finance on its own terms, a testament to the vision embedded in Bitcoin's code.
