Feel free to ask for support of your favorite currency. Else, just implement it (eg: to add Litecoin logo):

Add 'litecoin' to the currency module config
Create the logo (png, 50x50px)
Name the file litecoin.png
Put it in the /public/ black-white/ and colored directory of the module
Restart MagicMirror

Notes

Data provided by coinmarketcap.com.

Endpoints update every 5 minutes.
Currently you can only display currencies listed within top-25 on coinmarketcap.com.
significantDigits only has a visible effect when set to 4 or more. It is useful for showing low-value coins (such as Ripple) at a higher resolution, rounding to more digits after the decimal point than the minimal 2. Rounding always keeps at least two digits after the decimal.

Feedback

It's my first module here after that I built a MagicMirror. I'm so proud of it and I have found a lot of interesting modules, including one similar to this, based on Bitcoin only MMM-bitcoin.
I am open to work on this project and to expand it to add other interesting features, and a bit of cool style too.
Leave me some feedback in the forum. Thank you!
