Halloween is traditionally associated with candy, but a lot of people decided to get creative. Some thought "Why should kids get candy when you could give them a can of sausages!"
We can think of a lot of reasons, but alright.
The search for the real inventor of Bitcoin is over. According to the video description, the man in the video is the real deal:
Australian entrepreneur Craig Wright has publicly identified himself as Bitcoin creator Satoshi Nakamoto. His admission ends years of speculation about who came up with the original ideas underlying the digital cash system. Mr Wright has provided technical proof to back up his claim using coins known to be owned by Bitcoin's creator. Prominent members of the Bitcoin community and its core development team have also confirmed Mr Wright's claim.
Wright seems completely uninterested in fame or recognition. He gruffly insists that he wants to stay out of the spotlight, so why would he do an interview at all? His reasoning, in what he says will be his one and only interview, is to put an end to the controversy surrounding the identity of Bitcoin's inventor for the sake of his family and staff.
