They are unofficial exchanges, so no URL there. But yeah check out coinsfera, bit oasis etc. or p2p on binance to cash out smaller amounts on a regular basis, probably safer anyways.
These unofficial exchanges are more suited for someone who needs dummy receipts from a company to justify bigger transactions. But feel free to pm me if you want more details.
It depends on your background,︂ and what you can come up with if questioned, so if you have knowledge about︃ a certain business or a degree that qualifies you to operate certain business activities, then︄ that might be easier for you to run and justify. But usually something like computer︅ consultancy, advertising consultancy, some form of business management firm, software design etc are all viable︆ options, and you could be getting clients from around the world since its remote work.︇ If you do plan to stay in the UAE for sometime and invest then you︈ might have other options available too like real estate for instance (a few brokers are︉ starting to accept BTC).
I remember reading some good replies on the forum when one︊ of the members was asking about setting up a company in Dubai and opening a︋ bank account etc. so you can check that out.
