South Asian countries such as India, Bangladesh, Pakistan, Afghanistan, Sri Lanka, some regions are economically very distressed. Bitcoin is an important topic for these regions. Some people in this region live very close to the poverty line. Due to which it becomes difficult for them to run parallel to the country. Through this platform the foreheads of the people of all these regions are being opened.
I think cryptos effect in these countries is rather limited, but then it is limited in most countries at the moment. The one really useful thing to people in these countries is how it can be used for overseas remittances, where family members are able to send money back that they earned to support families in these poorer countries. Crypto allows them to avoid scrutiny of sometimes unfriendly government financial authorities and also minimize transfer fees that can be very greedy from some banks. A lot of these countries will operate various types of black market as well, as the government is unable to effectively or without corruption provide certain services. However it often depends on having an internet connection which can be hard to come by in certain areas.
