Now this is new knowledge to me. Never researched to this extent. But then, why would a group of people's identity be shrouded behind a pseudo-name. Don't they want the recognition like any great scientist would? I wouldn't do something groundbreaking like Bitcoin and not want my glory to shine forth. Anyway, to each his own. I am sure they have their good reason for wanting to remain anonymous. By the way, your reply has given me insight how I should go about my research of this pseudo name, Satoshi Nakamoto. Thanks for your response.
