UK and many countries have double tax treaties with UAE where they use the "exemption" method, which means UAE sourced income is exempt from UK tax. On the other hand, Germany uses the credit method, meaning you will still have to pay full tax in Germany, since UAE tax is 0. This is when you are a resident of both countries.
Germany's residence test is also a bit different. It seems like you either spend 183 days in the country OR you have a place of residence available to you, even if you don't live there. One question is, what happens if you rent out a place by contract, and you cannot move back in otherwise. For example, you can buy apartments in Germany as Buy-to-Rent. Would that count as residence?
In addition, someone else posted a link that UAE considers some crypto as securities, and other utility tokens as commodities. For the record, Binance lists mostly utility tokens, so that involves a lot of crypto coins. UAE has 5% VAT on imported and exported commodities, so would having a business and personal residency in UAE help with this?
