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 ?

I feel bad for this news. Another country banned bitcoin, this is not good. Even though it banned today I knew that it is still open for some possiblities and opportunities when it comes to the innovation of the future in technology, as of now for sure they can not see their country that cooperate in using bitcoin. I knew someday it will change, they will have another reason to change their mind and accept bitcoin as one of their currency.
