Dubai –

Ahead of U.S. President Donald Trump's Gulf visit next week, his son Eric was promoting his crypto firm in Dubai, while Don Jr prepared to talk about "Monetizing MAGA" in Doha.

Last month, the Trump Organization struck its first luxury real estate deal in Qatar, and released details of a billion-dollar skyscraper in Dubai whose apartments can be bought in cryptocurrency.

In a monarchical region awash with petrodollars, the list of Trump-related ventures is long and growing. However, the presidential entourage is not the only party cashing in, analysts say.
