According to conspiracy theory, Is it possible that the bitcoin was created by governments to gain financial strength in the modern world?
That would be the dumbest conspiracy that I have ever heard. Even if it is true then we should be on the mass adoption stage in the last few years but we are not. Only an unselfish person or group of people would ever made bitcoin. Why will the government ever need btc when they can all have the power of fiat which they can print as long as they want.
