I think that South Korea should be on the list as well.
They have a lot of blockchain hubs created all around the country. The most important country of all is Japan where they clearly have adopted the blockchain technology by placing crypto ATMs in a lot of spots.
Besides South Korea, Philippines should be listed as well as those 4 that you've stated. Because here in the Philippines, the government doesn't care about how cryptocurrency regulates in this country. They just get taxes or fees in the exchange so that they will still benefit those people who uses crypto.
