We Will Spend Credits in the Future: While somewhat played straight out towards the Rim Free Zone with its ergcred, a currency whose name is never abbreviated at the front, for the most part we will spend exvals in the future. (See: Global Currency).
This may have something to do with the way that those proposing currencies named “credit” were, somehow, all accidentally lynched by rampaging mobs of accountants who knew exactly where this would end up. Like the trope example says:
“So as you can see, on 10 June we credited 35 credits to your line of credit and debited 7 credits from your debit card. Then we debited 8 credits from your line of credit and credited 14 credits to your debit account.”
