I strongly agree on your opinion that, no one can manage bitcoin including the government and can not be added anymore amount. And adding also my opinion that, Bitcoin has the smartest an best developers in the world who have been coding and working on forms of digital cash since the 90s. In addition, Bitcoin is different because it was first and because it has the most support and bitcoin has developed infrastructure and sparked the fire that is our cryptocurrency. On the other hand, Bitcoin is not a currency but also Bitcoin is considered as a new business hub, I think that is the difference between Bitcoin and other conventional currency.
