The UAE has gone one step further, it has created so-called "financial-free zones," or areas that are mostly tax-free and heavily regulated. The UAE positions themselves as a safe port for cryptocurrency companies.
Of course this is the latest development that needs to be listened to and used as a momentum that more and more big countries are also playing a role in crypto. We will wait for developments in the surrounding countries, which are a bit too closed off.
You can't draw a such a conclusion from an article made to attract investors, for a currency (Crypto or Fiat) to be a legal tender of any sovereign nation it has to have a law backing it up. From what I know there is no law in the United Arab Emirates UAE backing Bitcoin as a legal tender so the answer to your question is no.
They don't specifically state that in all countries it is free and legal tender, but Dubai Financial Services Authority is planning to create a crypto regulatory framework as part of its business plan. The authority has issued a series of regulatory approvals for the crypto industry so far, while Dubai is home to several crypto-free economic zones.
but this is a step forward that the UAE has taken to ensure that they are ready for all parts of the country to accept once the regulations are finalized.
