That's why bitcoin is the mainstream already because i believe majority of the total population of the world already know about bitcoin and the cryptocurrency stuff and i believe that bitcoin is already known to all the countries in Asia now. That's a good news because the more people got to know about bitcoin and the cryptos, the bigger chances of people to be attracted to invest on them.
All the countries in Asia might know about Bitcoin, but it is a different question whether Bitcoin will be able to survive and flourish there. We have seen that China has attacked Bitcoin, India has more or less strangled Bitcoin. Thailand has not acted against Bitcoin yet, but let us see how it deals with cryptocurrencies in the future once it becomes stronger.
