Following up to your above post, Lucius, perhaps Croatia was one of the first countries to really get into expanding bitcoin offerings through its post offices.

I just noticed that Daniel91 started such thread on the topic of the Croatian post office offerings in July 2019.  Initially it appears that the offer was only in one post office, and they would buy bitcoin and 4 other cryptos (aka shitcoins) with a 4% fee.  I noticed that you have a few posts in that thread too, Lucius.

Danial updated the status in January by asserting that bitcoin offerings in Croatia post offices had expanded - even though it started out as a kind of pilot project.  There was a notice that issued in mid-December that described that the expansion had gone to expanding the selling of bitcoin and the four other cryptos and expanded from 3 post offices to 55 post offices, and there seems to be some plans that the ability to buy (also) will be added at a later date, soon.^tm  You could translate this article to English.
