So how can it be possible for BTC to ascertain this great height of advancement?
Because of this your previous post you made on this same subject matter, you already have an answer to what you're asking even though you're seems not to be aware of that, bitcoin being a decentralized digital currency alone is what people can use to win over the use of fiat and there's nothing the government can do about it.
Now, the governments are in charge of the banks and other centralized monetary systems in a centralized networks while BTC and the cryptocurrencies are decentralized networking system of transactions which obviously the governments has no place of power on it.
Or should we just scrap that thought that BTC would take over the world in a global financial transactions trends and just say BTC would gets to its limits of authorized existence somedays in the future?
I don't understand if you're exercising doubt here or fear about bitcoin existence, we are already on the fourteenth year of existence and adoption with bitcoin now, government could not stop it, not anymore, just know this that bitcoin has come to remain ever valuable digital currency.
