In the foreseeable future, each developed country will create its own crypto currency, provided by the national currency.
You cannot be sure of this, and there is no fact that points to this, apparently the only country making such claims happen to be China,i do not see the reason why countries would create it's own cryptocurrency,when they can manipulate their very own fiat currencies..
How much can this contradict the very idea of Bitcoin as a free, decentralized system?
Even if such creations happen to come into effect,they will just be creating some other Altcoins/shitcoins and it has absolutely nothing whatsoever to do with the bitcoin,how it works or it's nature..
We already have over 2000 Altcoins,they will just be additions to those numbers
That is true, altcoin is just another currency and Bitcoin is still bitcoin, even though we have a lot of altcoin most of them are just shitcoins, and I think if country will create more, then it will be an additional shitcoin.
