In my opinion the government has very big role in the development of bitcoin. The same as with the security exchange trading that has been brought to the next level with the government promoting it and anticipate the demand from the currencies all over the world. If only the government will meddle and take charge also the bitcoin system then for sure many will going to trust the system.
In my country the government does not carry out development that can increase the use of bitcoin for the community, because in principle bitcoin is prohibited as a means of payment.
But bitcoin is not prohibited for investment because in my country bitcoin is included in futures trading. For more information, trade in bitcoin is taken from overseas sites, especially those from developed countries.
