Bitcoin has become like a golden fish that can't hide. In the midst of many other assets, bitcoin is the one that defies the detects of  regulation and so no form of direct regulation will limit the growth of bitcoin. Gold, silver, copper and other derivative assets are directly regulated but bitcoin is not. Therefore whatever decision by fed on bitcoin will atmost drag the price briefly down but it will correct it self after a while and that tells us self sustaining ability of bitcoin against the government. The banking system can not be reliable because it has been exposed of corruption through government third party standard making it difficult for bitcoin to be made irrelevant, the relevance of bitcoin is found on the purpose which it is fulfilling already.
