React Bitcoin Monitor

An app that monitors changes in the Bitcoin Price Index (BPI).

By default, the BPI will be shown for USD, GBP, and EUR. Optionally, one can select ones own currency to display in addition to the 3 aforementioned currencies.

Bitcoin Monitor makes use of the CoinDesk Bitcoin Price Index API. Go here for more price information by CoinDesk.

Go here for live demo.

The application is composed of the following components:

• Header - A heading that displays application title

• BitcoinMonitor - The primary (root) component that manages state for itself and all underlying components. It is also responsible for connecting to BitcoinService to retrieve Bitcoin Price Index data.

• Display - Displays the Bitcoin Price Index data for USD, GBP, and EUR as a default. Also allows one to select a currency as a fourth price to monitor.

• Indicator - Used by the Display component, it displays an indicator that shows if the current price is up or down from previous price.
