In the foreseeable future, each developed country will create its own crypto currency, provided by the national currency.
How much can this contradict the very idea of Bitcoin as a free, decentralized system?
Need cryptocurrency state control?
Not sure the government will control bitcoin, even though they plan to release their own crypton but I'm sure they will follow the workings of the crypto world that cannot be controlled and let it move according to demand.
If they won't follow the sole purpose of bitcoin/crypto will be disregarded, they can create their own ruling inside their jurisdictions but not inside the entire market of crypto, adopting and creating their own coin can be helpful to their economy as an alternate currency where they can deal using the system to transact all over the world.
