what does crew captain do in blox fruits

In Blox Fruits, the Crew Captain is an NPC that sells crew slots for 2000 in-game currency. If you are the captain, you can purchase one more crew slot per purchase, and you can have up to 30 slots. A crew is a feature in Blox Fruits designed for a set of individuals who work collaboratively. Before the player can create their own crew, they need to join an existing crew or be invited to one. Crews can participate in various activities such as boss battles, quests, and PvP. Therefore, the Crew Captains role is to sell crew slots to players who want to create or expand their crews.
