but this is just my opinion, so if I am wrong I apologize.
Thank You.
Yes, you are a bit right-money laundering, terrorism and financial frauds are certainly present in the bitcoin. But no more than the government itself can afford to do what it wants with money. They are simply very much afraid to lose control over financial means from which they collect taxes on social projects (I'm writing about very developed countries without corruption). And these countries will still have to legitimize bitcoin - because it's the future, and if they do not they will lose everything ...
