Governments want to us to spend the money they print and control. They also want to be able to tax it and track it as much as possible.
So what are you saying? We all know these things, can we stop it? No. Crypto currencies is decentralized, and with this these government can't tax bitcoin. But there are countries that can tax bitcoin, but not entirely bitcoin users but to how they will be accepting it. I read that if a company agrees to pay bitcoin to their employees, it will be under the incomd tax law where employees will be deducted a certain amount to their salaries.
