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, show how much the price of bitcoin is at the day X+N compared to dollar at the specific day X?

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.2804:7F2:68C:C9BA:BD84:116:CB13:FB88 (talk) 02:21, 27 February 2021 (UTC)[reply]

The notion of "the value of a dollar" increasing or decreasing requires a reference scale that is presumed to be stable. Perhaps the Big Mac Index? Unfortunately, it is not updated daily, but I suppose this index varies slowly, so I guess it could be integrated with the U.S. Dollar Index to take account of daily fluctuations. --Lambiam 10:58, 27 February 2021 (UTC)[reply]

The value of a bitcoin is exactly what someone (i.e., the market) will pay you for it. In that regard, it is an example of the “greater fool” theory: there is a fool out there, greater than I, who will pay me more than I paid for this financial instrument.

Delaware and Puerto Rico as tax havens?

Puerto Rico and especially Delaware have a reputation as corporate tax havens. What exactly makes people consider them as such? Is Puerto Rico a tax haven for individual income in addition to corporations as well? StellarHalo (talk) 21:41, 27 February 2021 (UTC)[reply]

You linked to Delaware, where you will find the answer for that state at Delaware#Incorporation in Delaware and the linked article Delaware General Corporation Law.

The Puerto Rico article, however, does not contain the word "haven". --142.112.149.107 (talk) 22:35, 27 February 2021 (UTC)[reply]

The Investopedia article on Delaware corporations and taxes really says it all much better than I could relate here. 69.174.144.79 (talk) 01:55, 28 February 2021 (UTC)[reply]

Here's an article about Puerto Rican tax policy [1]. It is indeed looking to attract companies through lower corporate taxes, as well as wealthy individuals willing to cut ties with the mainland for tax avoidance purposes (article on that particular policy here [2]). In both cases, it appears to be a relatively recent phenomenon. Xuxl (talk) 21:29, 28 February 2021 (UTC)[reply]
