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.
== Installation ==
- Upload the contents of the plugin .zip to the
/wp-content/plugins/ directory
- Activate the plugin through the 'Plugins' menu in WordPress
- In the 'Widgets' menu in WordPress, place the widget where you want it to appear on your site
- Verify that the plugin's settings are what you want in the widget menu
== Frequently Asked Questions ==
Can I change the look of the widget?
Yes, simply modify the included crypto-ticker.css file, located in the plugin's /css directory.
What about support for other cryptocurrencies?
I may add the smaller altcoins in the future if there is enough interest. If you can't wait, adding them yourself should be a trivial task; just keep in mind that because of the way the btc-e API is set up, each additional currency means an additional request, which will impact performance on cache misses. If I do decide to add the other altcoins, I'll probably re-write the widget so that the requests are asynchronous.
I have a referrer ID at Coinbase. Can I use it?
Yes! Version 1.2 and up allows you to enter your Coinbase referral ID in the widget settings. Please note that if you don't have your own referral ID, a default one will be used.
The ticker is showing different prices on all of my site's pages, and/or doesn't seem to be updating - help!
You most likely have a Wordpress caching plugin installed that is either misconfigured or out-of-date. Make sure that you're running the latest version. Older versions of W3 Total Cache will cause this problem (the most recent release should be fine).
