How does PAXG make money?

Inquiring minds want to know: How does PAXG, a digital asset representing physical gold, actually generate profits? Is it through traditional mining operations? Or does it leverage the blockchain technology for innovative financial services? Does it charge transaction fees or rely on appreciation of its gold-backed value? Given the uniqueness of PAXG, I'm curious to understand the underlying business model and revenue streams that enable this digital gold asset to generate income. Could you elaborate on how PAXG turns its gold-backed promise into real-world financial gains?
