Picking a nit on a presumed half-joke: you may make friends among the SI (metric system) guardians if you spell the unit names in lower case: "gavin", "satoshi", etc. Compare with "watt", "tesla", "farad" (rather than "Watt", "Tesla", "Faraday").
The symbol may be an uppercase letter, possibly followed by a lowercase letter, eg. "Gv" for "gavin" (compare "Hz" for "hertz"); but avoid combinations that may be confused with prefix+lowercase unit symbol, like "Gm" for "gigameter" or "Mb" for "megabit".
