I think that the government and bitcoin is not cooperating. With mutual work, I think the flow of investment would have increased significantly, since people would have some kind of guarantee. Bitcoin could infiltrate the all vcery large volumes. So we wait.
Its a well known fact that governments of any country whether they are a liberal or conservative one, dont like it when they are not in control of everything that happens in their country but they are also quick to reealize that though they may not be in control of everything if the thing is beneficial to the country they will be willing to okay it for the sake of eveyone and I believe bitcoin falls in this scenario.
