"Patrick Paige and Carter Conrad, who run a Palm Beach County business called Computer Forensics, LLC, in which Kleiman was also a partner, formed their own suspicions about Satoshi’s identity after receiving a string of bizarre communications from Wright following Kleiman’s death in 2013

The next communication that Paige and Conrad received from Wright was stranger still. Emails provided to Gizmodo, the authenticity of which were confirmed by Paige and Conrad, show that in February 2014, 10 months after Kleiman’s death, Wright emailed the pair to tell them about a mysterious project he’d been working on with their friend. As part of this undertaking, Wright wrote, Kleiman had mined an enormous amount of bitcoins—an amount “too large to email.” Wright asked them to ensure that Kleiman’s computers were safe, and to check whether their hard drives contained wallet.dat files, the pieces of software that contain bitcoins and their owners’ account information. On a subsequent phone call with Wright, a baffled Paige asked for more information about the partnership with Kleiman. After that, he said, Wright assumed a clandestine tone. “Can I trust you?”

According to Paige, Wright eventually told him that Kleiman was the creator of Bitcoin. Later, he clarified that the cryptocurrency was invented by a group of people which included Kleiman. If that was true, Kleiman was likely sitting on a fortune when he died in April 2013—even if he were in possession of only half of Satoshi’s fabled million-bitcoin stockpile, that would have been worth about $65,000,000 at the time of his death. Wright made clear to Paige that he wasn’t after the money—he only wanted to make sure that it made its way into Kleiman’s estate and didn’t sit gathering dust in a digital vault.

Wright stopped calling and emailing them after he made contact with Kleiman’s brother, the executor of Kleiman’s estate. “We knew one day a reporter would come calling,” Paige said. “But we left it at that.”
