To get a crypto license in Dubai, businesses must register with a relevant authority like the Virtual Assets Regulatory Authority (VARA) or the Dubai Multi Commodities Centre (DMCC), comply with strict regulations, and submit required documentation such as passport copies and proof of address. The process involves selecting a free zone or authority, defining your business activity, preparing necessary documents, and paying fees, which can range from AED 15,000 to AED 40,000.
