I may not know the country that you are from but I believe your country has its own currency which is generally accepted as a means of payment of goods and services. The question here is this, have your local currency that is used in your country not been used to commit any financial crime if yes, why is it still accepted by the government of your country hence the educated and uneducated people still uses it for transactions? PS, I think most countries like your own are yet to accept Bitcoin because they are scared since they can't control it and the people involved in it not because people are using it for financial crimes.
