For all price fanatics I have setup a simple price grabber that get's the ICO amout from ico.lisk.io and does the proper math to calculate the lisk price in satoshi and USD (bonus not included).

~~Does this image update itself?~~

Okay, it does. Awesome API-magic. Could you please make the stuff public? Would like to change the formatting and design of this image.

P.S.: Why did the price fall from 2608 to 2584? Shouldn't it increase only?

If crypti price drops lisk value will drop, if btc drops lisk value will drop.

Here is the source code, all commented for easy understanding:

Code:

//http://simplehtmldom.sourceforge.net/
include_once('simple_html_dom.php');

//GET HTML FROM ICO.LISK.IO
$html = file_get_html('https://ico.lisk.io/');

//GET CRYPTI AND BITCOIN PRICE
$priceXCR = json_decode(file_get_contents("http://coinmarketcap-nexuist.rhcloud.com/api/xcr/price"), true)["btc"];
$priceBTC = json_decode(file_get_contents("http://coinmarketcap-nexuist.rhcloud.com/api/btc/price"), true)["usd"];

//COUNTER TO KNOW WHICH COIN IS WHICH
$counter = 0;

//SETUP PRICE VARS
$bitcoinICO = 0;
$cryptiICO = 0;

//LOOP THRU ALL SPANS IN ICO.LISK.IO
foreach($html->find('span') as $element)
{
//FILTER FLOATS ONLY
$number = preg_replace("/[^0-9\.]/", "", $element);

if(is_numeric($number))
{
//0=BITCOIN AMOUNT, 1=CRYPTI AMOUNT, 2=SHAPESHIFT AMOUNT
if($counter==0) $bitcoinICO += $number;
else if($counter==1) $cryptiICO += $number;
else if($counter==2) $bitcoinICO += $number;

//INCREASE COUNTER
$counter++;
}
}

//CONVERT CRYPTI AMOUNT TO BTC
$bitcoinICO+=($cryptiICO*$priceXCR);

//CALCULATE LISK PRICE AND CONVERT TO SATOSHI
$liskPriceBTC = ($bitcoinICO/85000000);
$liskPriceBTCRound = round($liskPriceBTC*100000000);

//CONVERT LISK PRICE TO USD AND FORMAT TO 5 DECIMAL PLACES
$liskPriceUSD = number_format((float)($liskPriceBTC*$priceBTC), 5, '.', '');

header("Content-Type: image/png");
//OPEN LISK LOGO
$im = imageCreateFromPng("/var/www/html/lisk/lisk.png");
//DEAL WITH OPACITY
imageAlphaBlending($im, true);
imageSaveAlpha($im, true);

//SETUP TEXT COLOR
$text_color = imagecolorallocate($im, 0, 0, 0);

//ADD TEXT TO LISK LOGO
imagestring($im, 3, 120, 95, "1 Lisk = " . $liskPriceBTCRound . " Satoshi", $text_color);
imagestring($im, 3, 120, 110, "1 Lisk = " . $liskPriceUSD . " USD", $text_color);

//SAVE IMAGE
imagepng($im, "/var/www/html/lisk/lisk_price.png");

//CLEAN BUFFER
imagedestroy($im);

?>

crontab -e
