What is the credit limit on the black card?

I'm curious to inquire about the credit limit on the illustrious black card. As a holder of such a prestigious financial instrument, I'm sure the credit limit must be substantial. Could you elaborate on the specifics? Is there a standard limit that applies to all black cardholders, or does it vary based on individual qualifications and spending habits? Additionally, what factors determine the credit limit, and is there a possibility of increasing it over time with responsible usage? I'm eager to understand the full scope and benefits of this exclusive card.
