What is the entry fee for MPL?

Excuse me, could you please clarify what MPL stands for? Assuming it's a particular event, platform, or service within the cryptocurrency and finance realm, I'd like to inquire about the entry fee associated with it. Is there a specific amount that needs to be paid in order to gain access or participate in MPL? If so, what is the current rate, and are there any discounts or promotional offers available at the moment? Additionally, is the entry fee subject to change, and if so, how often does it get updated? Thank you for your assistance in clarifying this matter.
