The one thing you have to remember about people from conservative communities ( especially islamic ones) is that they are used to a specific way of doing things. The if it ain`t broke don`t fix it model is very strong there, thus being open even to the idea of new thins like crypto currencies and  ICO`s is something unconsiderable. At the worst case you get some islamic people with maybe a lot money not investing in your crypto stuff, but that doesn't make this guys biased opinion an opinion to follow and base your choices on, especially since he is probably born rich.
