I doubt that you want to use local provider BitOasis that charges all in all around 10% fees.
However beside of Mashreq and Arab Bank no bank is official claiming to be crypto unfriendly.
See attached the confirmation of Kraken as well.
First of all we and many clients have good experience when it comes to using the personal account organic that means you pay yourself a salary from the Business Bank Account of your own company and invest this money in Cryptocurrency via Kraken and withdraw this funds at a later stage from Kraken to the same Personal Bank Account.
In your thinking is a mistake - you need a reason to open the personal bank account in the UAE as well. You need to show either your own company or a salary
certificate or you need 7 figures and want to invest in UAE in lets say real estate. Only mentioning you want to open the Personal Bank Account for unspecified investments won't satisfy the bank to open the Personal Account for you as well as for Crypto Trading only. This is like with all major high street bank - go and mention Crypto Trading only to HSBC, Barclays or Standart Chartered and they even open the account because they know they need to close it down sooner then later.
That's why we say use our innovative methods to go the route over the business earnings to have a Fiat On/Off ramp to avoid any problems at all.
