هل دبي مركز للعملات المشفرة؟

Could you possibly elaborate on the question, "Is Dubai a crypto hub?" I'm interested in understanding the basis for this inquiry. Dubai, being a global city, often attracts various industries and technologies. But specifically, what attributes or developments within Dubai suggest it might be a hub for cryptocurrency? Are there particular policies, companies, or events that are indicative of Dubai's crypto significance? Additionally, how does Dubai compare to other potential crypto hubs around the world? Your insights would be greatly appreciated.
