More number of people from Asian countries are getting into bitcoin usage this year. This has taken place as a result of covid-19 which made most of the people spend the days sitting in front of the desktop/laptop. Almost every country have got users while very few have got legalized support from government. 2021 needs to be more flourishing, because growth and the market adoption is rising good in the global market.
You're right! Covid 19 pushed people to learn about bitcoin and use it. After losing their jobs and quarantine period, they found some ways to make money on the internet and fortunately they found cryptocurrency. And Asian countries use more crypto probably because Asian countries have the largest Economy and are fond of trade.
China is currently the leader in Asia in terms of cryptocurrency volume. But other Asian countries like Japan, South Korea, Singapore and Thailand are also keen in crypto. And I believe adoption of bitcoin and other cryptocurrencies will increase more in Asian countries.
