It seems like something out of a hollywood blockbuster call it Battle of the Bitcoin: Beyond the grave. A new lawsuit shines a light on the mystery of just who is Satoshi Nakamoto, Bitcoin's allusive creator. Craig Wright who claims to be Satoshi is subject to a multi-billion dollar lawsuit from the estate of David Kleinman who is the assumed co-creator of the cryptocurrency that passed away in 2013. Kleinman's estate is asking 5 to 10 billion dollars which could put him in the top 150 richest people in the world.
