Setup a live tile with up to 5 currency pairs.
Pick any combination of currencies from a list of over 160 currencies, including Bitcoin.
The exchange rates are being loaded from Google Finance.
Experiment with different tile sizes and pick the design you like best.

To create the tile, just pin the app to your start menu, and re-size the pinned tile to the size you want it to be.
After you select your currency pairs, the tile will be automatically updated from the generic app icon, to the pairs you selected.
