In which I cannot remember if we might want to add other currencies to this tool.. do you think that there might be some value in that? I am sure some folks might appreciate looking at their own currency rather than USD (even though surely USD remains the dominant shitty fiat out of all of the various shitty fiats).
I could add fixed value of other currencies in today's rate
The chart of historical btc price in a hundred currencies is a bit complicated (doable, but high development time, even to find and fix the data, since 2010)
Even if it takes a decent amount of time, if it is helpful, then might it still not be a good thing to add.. and maybe some tools might only go back to certain dates, they might not all go back to 2010? We could potentially consider the easy currencies first and maybe if we add less common currencies, then maybe those currencies would ONLY go back as far as the date that the API allows.. but yeah, it still might get down to concerns about how much time needs to be spent and whether it is worth it? Maybe we could talk more specifically in PMs regarding how much time is "high development time?"
Just now I had to go back and look at your currency converter,
https://bitcoindata.science/bitcoin-units-converterand I did notice that that particular converter is ONLY dealing with current price conversions and so yeah that particular converter is not providing an option for historical conversions - yet I would imagine that there would be some sites that might do some limited kinds of historical conversions?
