In my conclusion I think bitcoin can change economy in my country. Many problems such as road construction, traffic, illegal drugs, and poverty will be have a solution if bitcoin adopt as a whole in my country for our economy.
I dont really think that bitcoin can do that for us or the country itself. Thats bazaar idea to think about as the constructions or amenities that you have mentioned here are handled by the government. From where the government get the money to build all that? Off course they take the taxes from us and they collect t each financial year end. Once they receive the money they start planing the country. However, bitcoin is not taxed yet or in many countries it is not even legal tender so there is no way it can help country's economy in that way.
