It used to be that some people bought properties on someone else's name with a
POA remotely but I wouldn't advise nowadays. Before
CRS took effect, you could have opened up an account in UAE remotely too but not anymore. Yes it might still be possible for you to buy a property in someone else's name by POA. There are some real estate companies who could arrange for you to
cash out your cryptos and bring it to UAE after cashing them overseas but directly buying through cryptos in UAE is not possible as of now. As long as you have lots of money there are ways to do everything. Ask people in
mentor group or CaptK.
