Topic: Is there a site showing the "day X bitcoin value" compared to same day Y dollar? (Read 151 times)

NOPE thats not what I want.

I will try to explain with analogy.

Imagine that at january first 2020 I was 2 times faster than my brother. PS: IMPORTANT!!!!!!!!!!!!!!!!!! I didnt said what was my speed or my brother speed just how fast I was compared with him AT THAT DATE.
Now imagine that at january first 2021 I was 4 times faster than my brother. Again I said, I didnt said my brother speed or my speed at that date, just how fast I am compared with him at that date.

Can we conclude that at january first 2021 I was 2 times faster than I was at than I was at january first 2020? NOPE, because the january first 2021 information is comparing it with my brother speed at january first 2021, not with my brother speed at january first 2020 (or my speed at january first 2020).

As some example, if at january first 2021 my brother became 10 times faster than he was at january first 2020, this means  I became 20 times faster [ (4 * (10*1)) / (2/1) = 20 ].

So the information I neeed at january first 2021, is not compare how fast I am compared to my brother current speed, by compared to my brother old speed , and so I will be able to find how fast I became compared to my past self.

I believe he's looking for a price/live analysis and chart site that will provide the old and new historical data of the cryptocurrency market price of the whole day (24hours change in price) or more, not the ATH price or fixed amount in the dollar and for the record coinmarkepcap (as showing in the below image) does provide the price of the market per seconds maybe the problem is from OP not knowing how to read the price chart. I have to see any site that provides such service even the block.

I'm not aware of a site that is specifically tailored to your needs, but I find it hard to believe that it doesn't exist. Like I said previously, it wouldn't be too difficult if you can retrieve the entire history of Bitcoin's price, either through the Blockchain or through the various charts scattered about online.
I understand where you coming from, but its basically just semantics. The majority of people use "value" as a way of saying the current conversion rate. The conversion rate would be far more accurate, but its less convenient to say. Its probably safe to assume in the majority of cases that when someone says "value", they mean conversion rate, unless they are specifically clear that's not what they are implying.

There isn't a unit that defines value and remains the same forever. The dollar is considered a medium of exchange and thus a unit everyone agrees on, AKA global reserve currency, but dollar is a monetary unit.

It usually confuses the people, but there isn't such thing as "value". Value is how significant is a commodity or good to you. Price is the monetary units that are required to buy it. A bottle of cool water costs around 50 cents, but you valuate it differently when you're on a desert and when you're home. But the price remains 50 cents, even if it can be essential to you, or useless.

Anyway, in order to do what you want, you'll have to combine bitcoin's and dollar's charts and do the analogous calculations (deductions). You would then have the chart you're looking for. It wouldn't be bitcoin's value, though.

So basically, you are searching for a site that would compare the value of Bitcoin to a fixed dollar amount from a specific starting point; so if Bitcoin was $1000 on the 1st of March, when checking its value few months later, we should compare it with the exact value of dollar at the time (1st March), so as to get the actual value change in Bitcoin overtime.

I do not know of any site that does this, probably cause the fluctuations of the dollar is minute when compared to Bitcoin and also one would need to have a specific time focus requiring the site to compute lots of information.
But, you can manually draw up a chart by considering changes in inflation rate, purchasing power of a particular currency and compare that with the current value of Bitcoin.

What I want is basically:

The value of coin/money change over time, so when talking about the value of money you MUST talk about the specific day you are talking about.

When you search at a site the value of bitcoin at day X, it will show: 1 bitcoin (its value at day X) is  1000 dollars (its value at day X too, remember dollars value change over time, so you MUST say its value, the site dont say the date but its implicit).

Then if you search the value of bitcoin at day Y it will show 1 bitcoin (its value at day Y) is 1200 dollars (the value at day Y too).


The problem is that since not only bitcoin value changed over time, but dollar value too, you CAN'T know how much the value of bitcoin changed compared to its past, you are just comparing the value of bitcoin at day Y with the value of dollar at day Y, not the value of bitcoin at day Y to the value of bitcoin at day X or the value of the dollar at day X.


Imagine you just know I was, at the date of january first 2020, 2 times faster than my brother is at this date. And then  you just know that at january first 2021 I was 3 times faster than my brother is at january first 2021. You can't just say that at january first 2021, I am 1.5 times faster than myself at january first 2020, because like me maybe my brother became faster or slower than he was at january first 2020.
If my brother as some example became 2 times faster than his january first 2020 version of himself, I would become not just 1.5 faster than I was but 3 times faster than I was.

The solution to this, is so to compare my january first 2021 speed not to his january first 2021 speed, but to his january first 2020 speed. To be able to see how fast I am compared to myself at the past.



What the site would do is something like that.

1-The user pick an specific date W, or the site select by itself an date W.
2-At date W the site will show the value of day W bitcoin in day W dollars.
3-At other days, lets say day N, the site will show the value of (day N) bitcoin  not in day N dollars, but in day W dollars.

If I understood everything correctly and Welsh's description was accurate enough, then the closest thing that I know of is the "Price Search field on Blockchain.com ^{[it's meant for something else but it also works for your case with a few workarounds]}".

• It doesn't have the functionality to count for a certain amount or have two input fields for the date ^{[unfortunately, you need to do those steps manually]}.

Use blockchair explorer (https://blockchair.com/bitcoin) to view the transactions and click the switch "USD-BTC" and the USD value should be the average value on that transaction's date, not based from the current price.
Then get the current USD value though other means.

I'm not aware of a website that provides everything that you want, if I'm understanding correctly, however various Blockchain explorers display the dollar value, and the Bitcoin amount at the time that it was sent. You could potentially, look at the ledger at the specific days you want to know how much it varied.

I imagine there is a website out there, though. I'm not just not aware of it. There's various chart websites out there which shows the entire history of Bitcoin value, and you could potentially use a USD history website to compare the two. As for one, that's a all in one place solution, that's not something I'm aware of. Unless, you count looking at exchanges price histories? As they usually have USD history, and Bitcoin history.

I do believe your looking for a all in one solution which does it all automatically though. such as:

1. Input Bitcoin amount
2. Input date
3. Returns dollar equivalent of that date
4. Compare previous output to a newly specified day

i.e
1. 1 BTC
2. 01.01.2050
3. $10,000
4. 02.01.2050
5. $20,000 (e.g +10,000 )

If the above is what your looking for, I can't imagine this not existing, since its a pretty simple implementation.

Is there any site that instead of showing how much the value of bitcoin at day X+N is compared to the dollar at the same day X+N, so, how much the price of bitcoin is at the day X+N compared to dollar at the specific day X?

At all sites I could find, if you look at the price of bitcoin at january first 2020, it will how much of january first 2020 dollars, this january first 2020 bitcoin is worth. So it will show as some example 1 BTC = 1000 Dollars, but its implied that it is saying 1 BTC (january first 2020 value of the currency) = 1000 dollar (january first 2020 value of the currency).

Lets call bitcoin B and dollar D, the site will sort of show this formula: 1 B = 1000 D.

The problem is that the value of coins, like btc, dollars, euro, or anything else.... changes over time.
At another date, lets say december 1 2020 the site will show 1 BTC = 1200 D, being implied that its saying 1 BTC (december 1 2020 value of the currency) = 1200 D (december 1 2020 value of the currency). The thing is, if the january first 2020 formula was 1 * B = 1000 * D, the formula for an another date will be ((1 * Y) * B) /Y = (( 1000 * Z) * D) /Y where Y is how much the value of BTC increased or decreased and Z how much the value of the dollar increased or decreased.
If at december 1 2020, it shows 1 B = 1200 D, we can't solve the equation ((1 * Y) * B) /Y = (( 1000 * Z) * D) /Y to find the value of Y, first because at 1 B = ((1 * Y) * B) /Y , the value of Y can be anything that is not 0, and at 1200 * B = (( 1000 * Z) * D) /Y is also not solvable, only being able to know that Y is not 0 and Z is 1200 * Y.

So, is there any site that allow me to compare the value of bitcoin over time, with the value of dollar at some very specific day X? At the previous formulas it would be finding the value of Y
