The info above is not correct. The dividend tax is 20% in Serbia.
The law from 2021 recognizes
crypto as "digital asset" but not as a tool for day to day use and payments. There are no crypto friendly banks as we are used to in other jurisdictions. However, yes, Serbia is indeed fantastic for banking, wide network of correspondent banks, no CRS, low banking fees, ability to get multicurrency account almost immediately,
asset protection vehicles such as endowments (trusts)... Also it is the only jurisditcion in Europe where you can confidently receive money from Russia and send money to RUssia...Even in roubles. Should anyone be interested in that.
