Yeah and i do think iceland should be on the list. i also think thailand is one of the most crypto friendly country. The goverments of thailand even make few crypto legal in thailand and they do think blockhain will have a good impact on businesses in the future. Most of country in EU is crypto friendly.
I see that the article was made March of this year and it was already updated. I don't know what's on the mind of the author but it's not totally the complete list that everyone can lean on if we are looking for information about those countries.
Just look on how many subjected against the information that it brought us here. Yes, most of the countries included are crypto friendly but they still lack a lot of countries. Also look at the comments below that article, too many to mention.
