Adding javascript script to header via functions.php

I just opened your website and checked your crypto.js is successfully embeded in your head. But you have some errors in your code that’s is why it’s not working.

Here is the code which i have found in your file.

jQuery(document).ready(function() {
<script type="text/javascript">
baseUrl = "https://widgets.cryptocompare.com/";
var scripts = document.getElementsByTagName("script");
var embedder = scripts[ scripts.length - 1 ];
(function (){
var appName = encodeURIComponent(window.location.hostname);
if(appName==""){appName="local";}
var s = document.createElement("script");
s.type = "text/javascript";
s.async = true;
var theUrl = baseUrl+'serve/v1/coin/header?fsym=BTC&tsyms=USD,EUR,CNY,GBP';
s.src = theUrl + ( theUrl.indexOf("?") >= 0 ? "&" : "?") + "app=" + appName;
embedder.parentNode.appendChild(s);
})();
</script>}

And this one is error free code replace this with your existing file.

jQuery(document).ready(function() {

baseUrl = "https://widgets.cryptocompare.com/";
var scripts = document.getElementsByTagName("script");
var embedder = scripts[ scripts.length - 1 ];
(function (){
var appName = encodeURIComponent(window.location.hostname);
if(appName==""){appName="local";}
var s = document.createElement("script");
s.type = "text/javascript";
s.async = true;
var theUrl = baseUrl+'serve/v1/coin/header?fsym=BTC&tsyms=USD,EUR,CNY,GBP';
s.src = theUrl + ( theUrl.indexOf("?") >= 0 ? "&" : "?") + "app=" + appName;
embedder.parentNode.appendChild(s);
})();
})
