Banking in Armenia may just become the "next big thing".
It's a country very similar to Georgia when it comes to banking - they are both open to foreigners opening bank accounts and storing their wealth.
Also, they're not applying the CRS standards, which means you have more privacy, in addition to the high interest rates and the possibility to invest in their real estate market.
What is interesting about Armenia is that they allow you to bank in lots of different currencies - euros, US dollars, and even Russian rubles, which may be a twist you were looking for.
