I am not familiar with Snow Crash myself and I read the Wikipedia page [1] on it and it makes sense what you're going for; but just want to say that for someone who was born in HK, seeing the term 港幣 really can only mean HKD in my head, and it's difficult for me to process that it means something else. Even as you keep the name Kong, have you considered calling this something else in Chinese aside from 港幣 specifically?
