CryptoBadger

Cryptocurrency Ticker displays current cryptocurrency prices (bitcoin, ethereum, and/or litecoin) on your WordPress site. You may select which quotes to show, in either USD or EUR prices.
Prices are fetched from coinbase.com using their API (https://developers.coinbase.com/).
Ticker prices are cached for a duration that you specify in the widget menu, to improve performance and prevent your site from making a ton of requests to coinbase.com.
