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 ? 
Probably because bitcoins in Sri Lanka have been so rampant that it actually started to take a toll of the economy of the country. We can never blame Sri Lanka for the move, it's because they are just protecting the balance of the economy. Maybe in time, once bitcoins have stabilized or Sri Lanka has made innovations to accept bitcoins, they can open their doors again.
