A CryptoCurrency Ticker, which will run on top of Rainmeter. Go to https://www.rainmeter.net/ and download the latest release, and install rainmeter.exe.
After that, download this: Cryptoticker_v 2.0.rmskin package, and double click, open with rainmeter.
And that's it! It should work.
Thanks to CoinGecko and Alternative for providing their APIs for public access.
Known issue/bug: sometimes, there can be a second bracket after the end of the price, mainly because I hardcoded the webparser string :P I was a bit lazy to figure out what to do.
This was my hobby project, and I did it just because I wanted a custom ticker, and it's working as I expected. If you catch the bug and figure out, feel free to let me know. I'll update. :)
Also, feel free to modify the code as per your needs. You can go to -> Rainmeter -> Manage -> Select the crypto windows ticker -> Edit. A Notepad will open with the code, so feel free to edit it if you want. If you mess up, delete the widget, and download again from here.
