On April 23, 2011, he sent a final known email to early Bitcoin developer Mike Hearn. In his message, the Bitcoin creator stated that he had "moved on to other things" and assured Hearn that the project was "in good hands." Satoshi has not been heard from since. There have been various speculations about Satoshi's whereabouts, with some presuming the Bitcoin creator may be dead.
