Let me make one thing clear once and for all  zbd wallet is based on bitcoin Bitcoin became popular all over the world because it is not affected by any country's sanctions and that is why it was created. America or any other country, organization and company in the world cannot embargo Bitcoin for another country. Because no country can own it
No company based on Bitcoin can say we serve these countries and we don't serve these countries. zbd wallet works against bitcoin rules. Their work is illegal. 
Why doesn't wallet of satoshi do this? I ask you, if you block the IP of countries under sanctions, then what is the difference between fiat currency and bitcoin?
