What's the credit limit?
The credit limit is dynamic and changes over time, even for the same person.
When a person PMs me for an amount of credits s/he wants to borrow, I accept or reject based on a couple of factors.
Those factors include, but are not limited to, my credit balance, how much I trust the person, his/her ability of earning credits, how much the person wants to borrow, is it a long-term or short-term loan, does the person like Touhou, etc.
