Adds a bar to the bottom of every page that updates Bitcoin, Litecoin and Ethereum in real time. You can select to see the price in either USD or EUR and you can modify the theme of the toolbar to fit your style. The bar is collapsible incase its blocking content behind it. You can also configure a quick shortcut to your preferred trading website. Uses the GDAX websocket API. Update .18: Preemptively added Bitcoin Cash as GDAX just listed it. This will read $0 until GDAX starts pushing the BCH data. Update .17: Fixed issue where sometimes the bar wouldn't show all 3 coins. Update .16: Improved websockets to reconnect if connection is lost. Should fix issue where CoinTicker stops updating if the computer has gone to sleep or lost network connection.
