April 23, 2026, marks the 15th anniversary of Satoshi Nakamoto's final known email, in which the Bitcoin creator announced his departure from the project. In the email, Nakamoto stated he had "moved on to other things" and expressed confidence that Bitcoin was "in good hands" with Gavin Andresen and the community. This message marked the end of direct communication from the enigmatic figure, leaving the Bitcoin community to continue developing the cryptocurrency independently.
