Not so simple. I asked about
buying real estate for
cryptocurrency, for example, from my wallet. What you are talking about is different. Here you must first transfer all the cryptocurrency to the exchange like
Binance, then change it to dollars there, open an account in a
Dubai bank, send these dollars from the exchange to a Dubai bank. There will be a lot of questions in this, incl. from the side of the exchange where you got your bitcoins from, as well as from the side of the Dubai bank.
Buying real estate directly with cryptocurrency looks much more interesting. Especially if you do not need to return money to the country of your
citizenship.
Buying real estate in Portugal sounds more better, including that you will get Gold Visa and will be able to have a good rent out income from your property in next 5 years, and after will get PT passport. For not european people this is good idea, IMO. Only one thing is a questions - how to buy real estate there for
crypto, directly.
