If there are governments have created coins with their own currencies, I think those coins will still be decentralized and eventually they who created the coins wont be able to control the coins like other altcoins bec
ause I'm sure the coins will move based on demands.
What are you saying? Every crypto currencies that is ever made is decentralized, the reason it is called a crypto currency. They will not be able to control it but they can do something to affect or influence it. The price moves on demand, yes but the reason it is a volatile crypto currency is because of its decentralization.
Well, it not every crypto currencies that are decentralized because the last time I checked XRP,NEO and EOS are both centralized coins and if it happen that the government of each developed countries create their own national crypto currency then they make it a centralized coin because we both knew the government like have power over things which is why they see bitcoin as threats.
