If we promote it as "auditing" instead of "mining", that should drive the difficulty down by making it sound boring! But on the negative side, it may attract Scientologists.
Speaking as an ex-Scientologist I'll comment on that. "Auditing" in a Scientology sense is pretty much unknown except to insiders, so if a Scientologist sees the word in general use he assumes it is being used in one of its regular English meanings and there is rarely any confusion. There *is* confusion of course when a cultie uses the word to a non-cultie who thinks it is being used in its regular sense. In other words, bitcoin miners
becoming bitcoin auditors
wouldn't make any difference with regard to the culties.
