The Bank of XP
The Bank of XP is now [un]officially open. [going official would mean taxes...] What we offer depends on what you need, what we accept depends on what you have. Everything has a price, but that price naturally fluctuates depending on the person in question. You don't come to us, we come to you.
The bank of XP has also started a side business that deals with a ... unique kind of currency, that may or may not be further detailed within the comment section of chapter 480.
