Can Bitcoin ever be use as other country currency and it will still maintain it decentralized digital currency?
IMHO, I believe it is not, because the government won't allow it to happen anyway how can you fit the centralized governance to the decentralized functions of Bitcoin, it's too complicated, thats, why both systems are, can co-exist without interfering with each other, with the current set up the government will remain using its traditional fiat or somehow they want to build CBDC or the digital version of its currency.
