Anyway, I haven't heard that it's possible to use crypto in UAE...especially in real estate, wow.
It's a thing in the country already. There are widely crypto use as payment as well aside from bitcoin and ethereum. People just need to choose escrow company to handle and okay for crypto transaction with the buyer/seller.
And you ideally need to be in Dubai / UAE if you want to invest in those properties and real estate. Using crypto for real estate is a good option but don't trust anyone if he ask for the real estate investment in dubai virtually online. You need to be on site to see for yourself that you are not being trapped for a fraud. Since crypto transactions are irreversible, you should be extra careful.
I saw some websites that are selling real estate for crypto across the world. We already have that option it seems.
