I think I have mentioned it several times the UAE banks are good for the retail banking and once you have 2-3M you go the DIFC and have a conversation with all the big banks that are located there.BVI is better than UAE in some cases. Depends on the business. Don't forget UAE is a sharia law country.
Also is safer to park assets in BVI company than UAE I think. I wouldn't keep my assets in UAE banks. I understand you are consultant of UAE matters, but UAE is not always best choice
When it comes to operating a business with retail banking and day per day transactions the BVI is simply not usable as they don't get any normal retail banking in reliable banks. That's why I mentioned the BVI is still good for Asset Protection and Wealth Management after you made your money.
