We actually dont know and who knows? Bitcoin online trasactions as of now is untracesable except i think in canada they said iits tracesable already but im not so sure yet. They said the tax of bitcoin in canada is 40% . Anyhow lets get back to the main question, basically internet has a lot positive feedbacks comapred to negative one just like bitcoin, lets say if this was used to do any crime act,i think there are more positive way bitcoin had offer to each everyone. The opportunities that has given people on which we earn in so man ways by workingon on it. There are always a positive and negative outcome in everything we do. Crimes are just always their because we cant control peoples attitude or what they think and do. I think thats the reason why every country Governments are very vigilant and skeptical with any crytocurrencies around the world. Lest just hope for the best and think positive.
