Last past months Sri Lanka's Main Bank (Bank of Ceylon) was banned cryptocurrencies in Sri Lanka. What do you think is the reason for that ? 
May I see the link to the information source?
It is a normal thing. Usually, those countries that do not know what bitcoin is just banning it instead of trying to understand what is that and how it works. Apparently, Sri-Lankan government and banks are lazy to conduct their research.
Precisely, the news is, but where did this information come from, no one knows, but then everyone is surprised where the panic mood comes from.
Prohibition is always easier than accepting a new one. It's not for nothing that they recommend introducing a younger generation into the government, which is not so biased about innovations.
