Bitcoin will not replace banks or the dollar. Not sure why people still believe this is even possible. US government is too powerful to let a tiny dot as Bitcoin come close to their giant currency that happens to be the main currency of the world.
And there's no possibility that bitcoin will be replace usd..
Yeah dollar is more powerful and popular in compare to bitcoin, and I don't see anything happening like that sooner or latter, dollar will always treated as a number one currency.
Yeah, dollar is being treated by people that it is the supreme currency of all currencies because USA is a powerful country.
If bitcoins become currency of all nations it will become a one world government.
That seems to be impossible as Government will only support their own currency and not any digital currency, they would choose the currency that they can control.
It is possible if the bitcoin will support by the government of that country even they have their own currency.
But it would be hard for people to start using bitcoin when the government implements it immediately.
