please make it appear on my win 10 taskbar right besides my city temperature

Sorry, but it should be:

    =RANDBETWEEN(30000, 60000)

(or randarray!)

Coingecko api has historical price lookups going back years and it is free to use. It would be cool to see a historical weather report.

I love this. Most crypto price interfaces are super complex and this is a nice simple take on it! Please keep in-mind that my critiques/feature requests are because I actually really like this =)

Piggy-backing... Contrast as a whole needs some adjustment - keep in mind that people's light situations drastically will affect (effect? hell I don't know) how readable text on a background is. I have a window behind my most used monitor which sometimes causes issues with light text on light backgrounds, or dark text on dark backgrounds. There's also color blindness, age-related issues, and many other situations in-which you will want more contrast than what has been implemented here. This is very low-contrast, and I think it wouldn't detract from the "clean look" by swapping some of your white/off-white text out with black/near-black/navy equivalents, and I promise you it will make this software accessible to more folks!

I also would love to see a general "cryptotemp" solution that allows this same thing for different currency pairs. ex: "https://cryptotemp.com/ETH-USD"

Great solution. Bookmarked. Sorry to nitpick!!!

Yes. I can see this being used for other financial instruments. For example, daily variations of GME could be visualized in this manner.

When can we expect golf ball size hailstones?

Just create an excel sheet and type

    =RANDOM(30000,60000)

Is this Opensource ?

Sure, past 7 days. But what about next 7 days? ;)

Is it possible to view a longer time horizon than 1 week?
