Well, I read that the most friendly countries to the crypto currency are: Japan, Germany, Estonia and Singapore. Most of all I like Japan, this is the country where I can even move to live, since there are a lot of interesting things there, besides loyal crypto laws.
You have missed out the super friendly countries like Malta, Gibraltar and now recently San Marino. I was also thinking Japan and Germany but they are not friendly towards everything. Malta and Gibraltar for example actually have pure blockchain laws that were enacted specifically for the industry needs. There is a big reason Binance moved two times and ended up in one of those spots!
I think that Malta is so friendly to crypto and any other kinds of investments, because their territory is so small and foreign investments and crypto free laws are the only keys to fill the budget and not turning into local branch of Congo, Uganda and etc.
