2018, Ira Kleiman, the brother of Wright’s late business partner Dave Kleiman, sued Craig Wright for allegedly attempting to appropriate the estate’s massive 1.1 million BTC holdings held in a family trust. These coins were jointly owned between Wright and Kleiman. Over the course of the year-long court battle, it appeared that Craig Wright was attempting to forge documents and lie, under penalty of perjury, in an attempt to claim right over Kleiman’s $5 billion in Bitcoin. These coins were acquired through Florida-based W&K Info Defense Research, a company the two used to mine during the early days of the protocol. Today, the judge reaffirmed that Craig Wright was indeed acting in bad faith in court. The judge rejected Wright’s testimony, found that he perjured himself, found him in contempt of court, and found that he falsified documents, according to court documents. That said, the judge did not determine whether Wright was Bitcoin’s creator, Satoshi Nakamoto. Though his behavior in court certainly calls into question his claims to the title.
