Modern Web Services

Provides ability for content author to insert a shortcode specifying an amount in either Bitcoin or a Fiat currency.
The plugin then converts this value in to the corresponding value using real-time exchange rates.
For example, I use this on my business site to display my hourly rates in my local currency, as well as in Bitcoin.
Includes a Tiny MCE plugin to assist content author in generating the shortcode.
Requires PHP 7.0+ due to scalar argument declarations.
<h3>For Developers</h3>
You can modify the html output generated by the plugin using a standard WordPress filter.
<pre><code><?php 
add_filter('format_bitcoin_convert_output', 'my_custom_filter_function');
/**
 * Modify Bitcoin-Convert's HTML output
 * 
 * @param string[] $output
 * @var string $output['beforeSymbol']
 * @var string $output['afterSymbol']
 * @var string $output['beforeValue']
 * @var string $output['afterValue']
 * @var bool $output['prefixSymbol']
 * @var string $output['symbol']
 * @var float $output['value']
 * @return string[]
 */
function my_custom_filter_function(array $output){
 // Place your modification code here.
 return $output;
}
?>
</code></pre>

Through the beautifully designed Crypto Dashboard you can import key data about your favorite cryptocurrencies to your site with ease.
Coin prices update in the background of your site every 15 minutes to always show the latest data from the markets.
CryptoWP comes with a drag-and-drop Widget and the <code>[crypto]</code> shortcode to instantly display your imported coin prices data on your site.
To show coin data in versatile ways, use the built-in Grid, List, and Text templates (more coming soon).
Unlike most cryptocurrency plugins, CryptoWP does not take over your admin panel with ads and bloated features and does not overwork your database by storing vast amounts of unused coin data.
CryptoWP only saves relevant coin data from the coins you choose to import to you site through the Crypto Dashboard. CryptoWP gets all coin data from the <a href="https://cryptocompare.com/" rel="nofollow ugc">CryptoCompare API</a>.
While we actively maintain this plugin for bug fixes and new features, we cannot offer support for any downtime by the CryptoCompare API. CryptoWP will never display a watermark of any kind on your website.
New features coming soon in <a href="https://cryptowp.com/" rel="nofollow ugc">CryptoWP Pro →</a>
