//HOW to Use: Just paste the below function definition on developer console while you are on Koinex.in
// Then call this function on console with Crypto Name like for Bitcoin: showInTitle('BCH')

var showInTitle = (function showInTitle() {
  console.log('Now you can call this function like: showInTitle("BTC");');
  var CryptoArray = ['BTC', 'ETH', 'XRP', 'LTC', 'BCH', 'GNT', 'MIOTA', 'OMG'];
  console.log('Available Cryptos are: ', CryptoArray.join(', '))
  
  return function (cryptoName) {
    var cryptoIndex = CryptoArray.indexOf(cryptoName);
