One Piece Money System

Traveling to the world of One Piece, I didn't see anything like Golden Finger. It's just that there's an extra mysterious store in my head. Sharingan, one magatama costs 10 million. Devil Fruit, starting from an unspecified 200 million. A Zanpakutō that has not yet been awakened will cost tens of millions. You can even buy characters, bloodlines, battleships, and arms... Money is not everything, but having no money is absolutely impossible. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
