if bitcoin was main currency, what's gonna be the BTC value?

[Webetcoins]

if bitcoin is the main currency I think this is the best news in the world it is also time for bitcoin to become famous all over the world and since bitcoin is the global currency, not all of it can be thought of as the value in an economy of a country so let's estimate it  based on how much we can buy in a B

Best news? No not really because not all countries or people loves bitcoin but they only used to using the standard currency and it will be very weird for them if BTC suddenly introduced as a main currency. BTC is somewhat popular now but BTC is going to be a talk in the town once this event happen but will will this event really happen? I have a doubts on this one  because it can look very complicated.

How do we know the value of BTC if there will be no more dollar and local currencies because they will be gone too once BTC takes place as the global currency. What will the pricing of the items? And how much BTC are we going to pay to buy them.

I've often thought about this as well.

If the currency goes away and BTC is adopted as the central currency for all what would it be worth?

If BTC becomes the main currency in the world, I am sure that the world has been changing into something great. This means that the mass adoption of Bitcoin and blockchain technology have been very spreading.
Using Bitcoin as the major currency in the world is not easy, moreover, this is decentralized.
The value?
I am sure that it will be as high value, as the dollar right now.
We have seen many cases where something becomes the major, the thing will have a very high value. Moreover, if all countries similarly accept this.
But will it be?
I am not sure about this.
For we know that there is a big power of fiat as the main currency in the world. Bitcoin may be one of the currencines, but not as a main currneyc.

I think Government Won't allow to happen bitcoin is main currency. So It's impossible to bitcoin main currency. Bitcoin is most popular and most valuable coin in crypto market. We already know that all coin price depends on bitcoin price. Bitcoin price now little dip i hope bitcoin price will be more increase in this year and i hope market will be green again.

Once the bitcoin will be used by more than 50% of the population of the world, it will no longer be in the control of the governments to stop the usage of bitcoin or ban it. Instead the governments will themselves buy it and those who won't have bitcoin in their reserves will be left behind.
We can continue to compare the price of bitcoin with USD but after a certain time, there wil be only bitcoins and no usd or fiat currency.

That is a scenario that can obviously happen, but it is not what many think, some have in their mind that BTC can reach values of more than $200k, and it is not bad, when looking at models like the S2F it can be seen that it is not an insane amount and that it can possibly occur, however taking into account the current situation, people will not see it that way but quite the opposite, that it will not be able to arise and that it will decrease, but for me, the value of BTC could not calculate it , because it would be like doing an appraisal of capital gains, which is very difficult to do.

I am inclined to think that the fiat will not disappear no matter how much its use decreases, as discussed above. Even when gold was used as currency, it coexisted with less valuable coins of other metals. Typically this will be a process where we see more and more use of Bitcoin for payments and less and less use of fiat.

So, going to what the OP was asking, is that it is so relative. As of today we compare Bitcoin to other currencies, mainly the dollar. If in the transition I was talking about earlier it became Bitcoin unit of account, it would be the other way around, we would look at how many satoshis a dollar would be worth at that point. And in absolute terms, in the unlikely event that all other currencies disappeared and only the Bitcoin remained, 1 BTC would be one BTC but the value would be measured based on the things we could buy with it.

Well, it is a possible conclusion but it needs to take time before that will happen.
I am always certain that bitcoin would never be able to replace fiat currency, and I have no idea what its value will be until it does. It may be used for exchange or purchase, but it will never be the main currency. If you are wondering what would happen if the government allowed it, I am very sure they won't let it happen easily, and there's no way for any crypto to be worth anything given the fact that there's no assurance or measure of its value.
In short, --bitcoin and fiat should always be there forever.

BTC was created with a new transaction system without a central authority. The BTC can be used in the future as the main currency that we gonna pay with. But what's gonna be the value of a main currency? What's the value of dollars or eur?

-Answer is: The dollar IS the value. The dollar doesn't cost anything. The dollar is the value.

If BTC is gonna be used in future, it not gonna cost anything, because the BTC is gonna be the value. It not gonna be like Bitcoin cost 50,000dollars... Bitcoin not gonna cost anything because Bitcoin IS the value. But that's probably not gonna happen. We not gonna pay with BTC but with stable coins like USDT...

For now base on what we can see and believe, bitcoin is coming up to the standard of the US dollar in the nearest future whereby it will be generally acceptable and adopted as a legal tender, though I cant say it will erase the US dollars from existence but likely to work along with US dollars as the world most recognized currency, bitcoin already is the leading cryptocurrency and the value cannot be exactly predicted as its volatile but can place a great significance other than US dollars in the nearest future.

If bitcoin is the main currency, then any government will absorb bitcoin as much as possible to be able to control it and only circulate in their own country centrally (blockchain is underfunctional). Maybe bitcoin can also be used as a reference for a country's wealth because it is a rare digital asset reserve.

Bitcoin will forever be an alternative even if it is legalized. It's not worth pairing with something that can be created infinitely.

They won't be able to do that though as they're going to need to circulate it because hoarding it won't lead them anywhere besides their economic collapse. If it's the only currency then that can only mean that the countries won't be able to keep bitcoin for themselves. I would say that bitcoin would be worth around a billion for it to be a currency used by every country because that's going to be a lot of countries.
