I've read that conjecture
It's in the right format (seemingly random characters and numbers, specific length), but unfortunately for the bitcoin theory, the computer world uses random character strings of standard lengths in millions of places. "Tokens" or "slugs" or "hashes" or whatever, they're everywhere.
Sometimes they carry meaningful information, as the result of encrypting real data. But other times the whole point is to be obsessively random, as in unique within a given universe of numbers. And if the programmer did his job right, you can never tell the difference from looking or analyzing the result.
