It is even possible that new exchange developers who plan to develop this potential will much prefer the UAE as their place because the absence of tax is quite profitable. Although in terms of regulations we never know how the taxation there is so far for companies that will be built there.
I'm not really sure for the exchange's tax but there's no personal tax on crypto for the ones who live in UAE. There's no tax on any capital gains from crypto investment or from trading, and that thing is really exciting for most crypto users. I don't know personally but I believe there could be some taxation for companies.
It would be reasonable, at least.
The amount they could get from bigger volumes from the companies would be greater than the one that would be taxed from ordinary folks, imo.
