if this works very well in a few years in the future, I believe a lot of countries will use Dubai as one of prime examples in fully adopting cryptocurrency into their governments. More than that, we might use Dubai as a further study in the regulation sector of how they implementing cryptocurrency in various economy aspects.
Or should Dubai step further by making a some kind of cooperation league between countries in utilizing and cryptocurency? (since Dubai is part of UAE and I believe is a city, probably it will best to use Dubai as a model city for other cities within UAE)
In this case, we are far from the actual adoption of Bitcoin even if all employees choose to accept Bitcoin as salaries. As I explained before, those who will choose to accept their salaries in Bitcoin will be of two types: either employees who want to allocate part or all of their salaries in the form of a risky investment and they most likely have enough deposits that enable them to secure daily living expenses in a way that allows the salary to be used for investment savings, and I can almost guarantee that most of them will be senior employees who enjoy high salaries, or those expatriate workers who may choose this type of payment in order to make a quick and cheap transfer to their home country. In any case, there is no room for direct use of Bitcoin, and therefore this initiative remains a fundamental question about what its feasibility could be, and if a court in Dubai can issue these decisions, can it, by the same logic, allow economic sectors, partially or completely, to accept Bitcoin payments.
I wasn't really paying attention on what you explained previously before you replied me, but now after I read it thorough fully, I understood your concern, especially the part when you mentioned about the salary, therefore it does make sense and I kinda agree with you. Although I may not able to answer your doubt for now, but for people who have invested their money and saving in Bitcoin, the thought of full adoption of Bitcoin would give a positive impact for them since it will affected the Bitcoin price drastically in a good way, it might sound selfish in some sense, but there if there is a way that would give more benefits to me, I'm onto it, and me for the adoption of BTC within a country would be very beneficial for me.
In addition, Bitcoin could be used as a payment options for people who want to invest their money, for people who don't, they could just choose FIAT instead, though it might not sound efficient, it could still help people to have better life saving or pension saving.
