I do. The USD is nothing more than an empty promise from a debt to the bone nation. At least in the long term. Dominating fiat currencies come and go, analogously with the top nation, in terms of world order. Before the US there was Britain, before that France. Maybe the next is China, who knows, but the US doesn't seem a sustainable nation to me.

Bitcoin is fuck you money. Fuck bureaucracy. Fuck debt. Fuck bailouts. I think people will appreciate this as time goes by.

No, because Bitcoin is too volatile and the BTC blockchain cannot handle billions of transactions per day. This question has been answered a billion times in the forum already. Just try to find the old forum threads about this topic, instead of creating another useless forum thread.
It's historically proven that the biggest empire in the world has the dominating currency. First it was the British pound in 19th century, and then the US dollar took over after World War 2. Maybe the Chinese yuan will replace the US dollar as a global currency, or maybe not. Who knows. Bitcoin doesn't have a big empire behind it's back. A bunch of small underdeveloped countries are Bitcoin-friendly, but that doesn't mean anything. The big powers must accept BTC as a legal tender, which is close to impossible to happen,

It has a possibility because some countries already use bitcoin as their legal tender, right? So it is really possible, but the question is when for sure it will take more years or decades, but also keep in mind that bitcoin was not made to replace our current fiat system, hence it was made so that we can transact or send and receive money online that can be easily tracked and has low fees. Due to technology getting better and cashless society getting introduced to us, it is really possible that bitcoin was one that will be used, or if not for sure, it was derived from bitcoin also.

No.

Just think of it. Will the government of each country allow a currency that they can't control to be the leading currency? I mean US dollar currently is the accepted currency worldwide and that as well is controlled by the FED and the government. Will they allow something like Bitcoin to be the currency of the world if they know that they can't control it.

Different countries might've permitted Bitcoin for transaction, but that doesn't mean that it will be the leading currency of the world. Don't jump to conclusions like that just because a few countries tried to permit it or accepted it. No possibilities, no chances, just no, no. It can still be used as an alternative payment though, but will not be a leading currency.

It is is difficult to predict with certainty that Bitcoin will lead the world currency market in the near future. However, Bitcoin has the potential to address many issues in the current financial system. Bitcoin's unique characteristics, such as its deflationary nature, ability to hedge against inflation, and fast and cheap transactions, make it a promising alternative to current fiat currencies. However, there are many challenges that Bitcoin and other crypto currencies face, including adoption, regulation and security. Therefore, it remains to be seen if Bitcoin will emerge as leader of the world currency market.

People's positive thoughts about Bitcoin are increasing day by day. There are already many countries that have legalized Bitcoin in their countries. Considering the convenience and security of using Bitcoin, many people now choose Bitcoin as their means of transaction. Many countries have recently joined Bitcoin. When Bitcoin is adopted by people all over the world, people will definitely transact with Bitcoin instead of paper money. Maybe Bitcoin can be used as an alternative medium to the US Dollar but I don't think Bitcoin can replace the US Dollar.

Paradigm shifts happen faster than you would imagine. We are at the beginning of hyper-inflation stage of the US dollar and this is not something that is just falling due, it has been band-aided over and over again for decades. Two rounds of bailouts (08' and covid) combined with monumental QE (money printing) for over 7 years (started in the EU in 2016, US following shortly after) and now there is really not much stopping it from hitting the fan in a very quick amount of time. It should have happened during covid, though the stimulus and printing combined with economic shut down and distractions allowed another dying breathe. Another decade of the US Dollar? Highly unlikely. I give it 5 years and no more. Even that I think is over-shooting it by a lot.

Bitcoin is officially legalized in some countries. But when Bitcoin is officially legalized all over the world, Bitcoin can lead the global market. But the popularity of Bitcoin is increasing day by day. There may come a time when people around the world will choose Bitcoin as their top currency for transaction and investing. Bitcoin may be expected to lead the world then. But it may not happen in our era. Maybe in our next generation or the one after that. But I hope one day Bitcoin will lead the world market.

A lot of people already do appreciate it, but there is still the threat that government will significantly undermine its utility, at least in the short and mid term. I guess we will see an interesting push for further adoption when the cryptocurrency industry gains in financial power and political influence. Banks have an incredibly strong lobby and governments and banks protect each other, finance each other for as long as the story can be sold to the public (or the majority of the public). I expect there will be a point where more and more politicians realize that there is more to be gained as a crypto proponent than there is as a fiat banking proponent.

The only way I see a cryptocurrency like Bitcoin ever become the leading currency in global markets is when some of the leading nations control the majority of the crypto industry, then fully legalize it, perhaps even make it legal tender and push adoption so hard that they can then shove it down other nations' throats.

I don't know whether gold reserves can effectively be hidden, but Bitcoin reserves could be hidden. In theory, the US or China could already control the majority of the Bitcoin supply without anyone knowing even vague numbers.

Bitcoin is already lead the crypto industry but to taking the the place of Us dollar It is very difficult to say how much time it will take.  But it is not impossible, in the future cryptocurrency will definitely be used as an alternative to the current currency, then Bitcoin will show its strength.

Not only just officially legalization in few countries Bitcoin take as their official legal tender And 5 more countries are expected to join the line. And I think until it becomes legal tender in most countries of the world, it will not be able to compete with the US dollar and it can really get our Next Generations.
