Craig Wright, the controversial Australian computer scientist and businessman, has taken the cryptocurrency industry by storm after he testified in the US Federal Court - West Palm Beach in Florida. He said that he was Satoshi Nakamoto, the ‘creator’ of Bitcoin.

Wright appeared in court for the $10 billion Kleiman case, in which he is alleged to have run off with millions of dollars worth of bitcoin.

On the stand, according to Cointelegraph, Wright said Satoshi Nakamoto was the character he played when authoring and disseminating the Bitcoin Whitepaper, which was published over an email thread for cryptographic hobbyists ten years ago, in 2009. However, he revealed that he is unfamiliar with what "bitcoin has developed into." But a number of crypto enthusiasts have called Wright a fraud, with one of the reasons being that he failed to prove that he is the "real Satoshi."

Moreover, in court on Friday, Wright brushed off tears, according to Bitcoin.com, saying he had invented Bitcoin for the millions of unbanked global citizens. During cross examination, Wright reiterated that he was Satoshi and that he wrote the original whitepaper.

“I set up bitcoin to be honest money, I set up bitcoin to fix the problems of every other digital cash that had been. Every single other one had fallen to crime. I thought I would set up the world’s first digital cash that would not fall to crime,” he said.

Wright added that he had nearly destroyed all the early bitcoins but the late Kleiman had persuaded him to keep it.

Furthermore, Wright said he is not able to produce a list of public addresses to his bitcoin holdings because the keys to his Tulip Trust were held by various people. He said David Kleiman, now deceased, had some keys and had told him to hand it over to bonded couriers. He also informed the court that some keys wouldn’t be available until 2020.
