For the relevant of what Bitcoin stand for which is it's decentralized nature and knowing what this stands for means the government will always hold on to what they can have full control of which is the fiat system hence Bitcoin can never come to this spotlight in other to protect it's relevance as a financial freedom and there is no system that can function without the existence of government, Bitcoin was never created to replace the fiat system and of course that wasn't the reason for it's invention but to work in hand with the fiat system and I don't ever imagine Bitcoin replacing any of the traditional money.
It's even delusional for anyone to think that Bitcoin is going to replace the fiat system, when the purpose was not that from the onset; rather, Bitcoin was created to give people a choice not to depend only on the fiat system. You can't completely survive in a country as a citizen without using fiat unless you don't want to deal with tax, and the government can't even permit such to happen.
