That's really good, Croatia is doing their best to spread the adoption of Bitcoin. Where I live, the states are not doing anything to help the adoption of Bitcoin, only individuals are doing their best, and the government are not saying anything to show where we stand exactly, though they have made a few comments that are a bit discouraging for those that are buying.
For now we watch with crossed fingers. There are walk-in centers where you can go to exchange your cryptocurrency to cash, a lot of them are here and apart from that, you can make use of online platforms. There are some fees attached though.
I don't think they you or your friends should wait for the official permission from the government in order to start some similar project in your country.
This project in Croatia started from one private company, not from the government.
They suggested business deal to the Croatian post and they accepted.
So, since Croatian post is state owned we can say that indirectly Croatian government accepted crypto but it's more business than political decision.
They sew possibility for the profit and accepted it.
