I don't want to believe government is furious just because they could not collect tax from transactions that involved bitcoin. To me the hostility of most governments to the development of bitcoin in their countries is based on various factors and tax could also be part of it. The way bitcoin and other cryptocurrency is structure right now it will be difficult for any government to be able to collect tax from bitcoin. The fact that it is a decentralized system makes tax almost impossible. However policy and regulations could be introduced that will make bitcoin taxable and also helps to solve many of the concern that has been raised by government as regards to bitcoin and cryptocurrency in general.
