As suddenly as Craig Wright declared himself the creator of Bitcoin, he now says that he won't attempt to prove it. In a strange blog post, the man who claimed to be Satoshi Nakamoto says that "I believed that I could put the years of anonymity and hiding behind me. But as the events of this week unfolded and I prepared to publish the proof of access to the earliest keys, I broke. I do not have the courage." He went on to say that the recent attacks on his qualification and character have taken a toll, and "I now know that I am not strong enough for this."
