1. A deceased man's family is claiming he helped create Bitcoin. The identity of Bitcoin's founder, an anonymous figure known as Satoshi Nakamoto, has long been a mystery. Now, a family in Florida is claiming their dead relative helped create the popular digital currency.

• The family of David Kleiman says that he, along with business partner Craig Wright, created Bitcoin in 2008 under the pseudonym Satoshi Nakamoto.
• Kleiman's family is suing Wright for half of Nakamoto's Bitcoin cache, valued at over $64 billion.
• Wright for years has claimed he created Bitcoin, and even though the token's creator could prove their identity by moving even a fraction of the cache of about 1.1 million bitcoins, he's failed to provide any evidence.
• Now, it's up to a jury to decide. Ten jurors were tasked with hearing the evidence and determining the fate of the 1.1 million bitcoins. We have a breakdown of the trial and the pseudonymous Nakamoto.
