The double standard we are talking about is not without a good reason considering the fact that bitcoin because of its decentralize nature can easily be use as a tools for money laundering.This is even made more worse because no government have direct control of bitcoin and you know those in power we naturally go against what they can't control. Government will always favour the banking system though it is the major tools used for money laundering because they are in direct control of the banking system through the various policies they established which the banking sector helps to execute.
