Where is Phemex based?

I'm curious about the location of Phemex. Could you please tell me where exactly is Phemex based? I've heard a lot about their services in the cryptocurrency space and I'm interested in learning more about their physical presence. Is it a company with a global reach or do they have a specific headquarters that they operate from? I'm hoping to get a clearer picture of their operations and the region they cater to.
