The number itself
Before the exchange claimed it, 6880 was just arithmetic.
Strip the ticker away and 6880 remains a number with ordinary properties: twenty-four divisors, divisible by 16 and by 43, sitting three steps below the prime 6883 — and, usefully for a web address, memorable precisely because it is not. Most four-digit numbers blur; 6880 has the rhythm of two falling pairs, 68-80, which is one reason it reads well as a domain.
In digit culture, 6 reads as 顺 (smooth) and 8 as 发 (prosper). A string that opens 68 and closes 80 gathers auspicious weight in Cantonese reading — see the 688 chapter for how that same digit logic echoes across the border in Shanghai's 688 prefix. This page's arithmetic is offered without comment; the culture page carries the folklore.[1]
