At present, the most powerful crypto is bitcoin. It may have been invented by Americans. Although Satoshi Nakamoto is a very Japanese name, many people analyze that it is only used to confuse us. Asia's current crypto industry is very developed, but this does not mean that Asia is the country that most embraces crypto. In many countries in Asia, such as China, South Korea, India and other countries, crypto is greatly restricted.
So I think, you can think that Asia is the most widely used blockchain, but the frontier of blockchain technology development is still the United States.
