Satoshi likes to double-space after a sentence is complete. This was the standard taught to typing or keyboarding students up until roughly the year 2000. Stylometry, studying a person’s literary quirks in writing, has been a ripe field for pondering the identity of Satoshi Nakamoto. It may be a stretch, but with few clues, this double-space idiosyncrasy has often been noted in places like /r/Bitcoin on Reddit. There has also been discussion about Satoshi’s tendencies toward British spellings of words, such as cheques for checks, neighbours for neighbors, decentralised or formalised with an s rather than a z, or use of the word “bloody.” Some say these British tendencies were for obfuscation—to fake the world. I personally think there is something to the British influence. His British usage reads very organicly and unforced. I interpret that Satoshi indeed had some British-influenced upbringing (e.g., Britain, or Canada or Australia or a British Caribbean island). Like micro-expressions in facial body language, wording, in organic thought or writing, becomes hard-coded. To not release those tendencies would require constant and extreme discipline. Of course, Satoshi just might well have those qualities and fool me right there! Regarding double-spacing, I tend to believe that the double-spacing may well hint at Satoshi’s age…he most likely learned to type when double-spacing after a period was standard. Revolutionary ideas have often come in history from people in their 20s or early 30s, but in this case, that seems too young. Typing this specific way, given the revolutionary thoughts for Bitcoin, and the technical skill acquired and necessary to create the code, as well as the polish in writing, Satoshi was likely not young when working on Bitcoin. Purely speculating, I would guess that he was likely around 40 when the whitepaper came out in 2008…meaning he was likely born around 1968, give-or-take a few years.
