Self-proclaimed Satoshi Craig Wright is accused of stealing bitcoin from his defunct business partner.

The District Court of the Southern District of Florida filed a lawsuit against Craig Wright, an Australian scientist who called himself the creator of Bitcoin Satoshi Nakamoto. The lawsuit alleges that Wright and his partner Dave Kleiman mined between 550,000 and 1,100,000 bitcoins within the period from 2009 till 2013. After Dave's death in mid-2013, according to the plaintiffs, Wright forged contracts and Kleiman's signatures and took over his assets.

According to court filings, Wright and Kleiman controlled about 300 thousand and 700 thousand bitcoins respectively. They were held in trusts set up in Singapore, the Seychelles Islands, and the U.K., the suit says.

“It is unclear whether Craig, Dave, and / or both created Bitcoin,” the complaint reads. “For reasons not yet completely clear, they chose to keep their involvement in Bitcoin hidden from most of their family and friends. It is undeniable, however, that Craig and Dave were involved in Bitcoin from its inception and that they both accumulated a vast wealth of bitcoins from 2009 through 2013.”

The lawsuit was filed by Dave's brother, Ira Kleiman.

Craig Wright commented on the claim saying one word: “Greed.”
