1. Go to this link http://freebitco.in/?r=2937030 and then login. (I prefer that you use google chrome)
2. After logging in, claim free btc by clicking the FREE BTC button above of the page
3. After claiming the FREE BTC, click MULTIPLY BTC button and then select Manual Bet
4. Copy the code below because it will really help you earn alot of btc

bconfig = {
  maxBet: 0.0002200,
  wait: 1000,
  autoexit: 0.00001,
  want: 0.000014,
  toggleHilo:false,
  startbal: 0,
  won: 0,
};
hilo = 'hi';
multiplier = 1;
rollDice = function() {
 
  if ($('#double_your_btc_bet_lose').html() !== '') {
    $('#double_your_btc_2x').click();
    multiplier = 1;
    if(bconfig.toggleHilo)toggleHiLo();
  } else {
    $('#double_your_btc_min').click();
    multiplier = 1;
  }
 
  if (parseFloat($('#balance').html()) < (parseFloat($('#double_your_btc_stake').val()) * 2) ||
    parseFloat($('#double_your_btc_stake').val()) > bconfig.maxBet) {
    console.log($('#double_your_btc_min'));
  }
  if (parseFloat($('#balance').html()) < bconfig.autoexit) {
    throw "exit";
  }
  if (parseFloat($('#balance').html()) > bconfig.want) {
	var num = parseFloat($('#balance').html());
	bconfig.want = num + 0.00000030;
	bconfig.autoexit = num - 0.00000420;
  bconfig.won++;
  var total = num - bconfig.startbal;
	console.log('Setting bconfig want to: ' + bconfig.want)
	console.log('Setting autoexit to: ' + bconfig.autoexit)
  console.log('Total won: ' + total + ' BTC')
  }
 
  $('#double_your_btc_bet_hi_button').click();
 
  setTimeout(rollDice, (multiplier * bconfig.wait) + Math.round(Math.random() * 1000));
};
 
toggleHiLo = function() {
  if (hilo === 'hi') {
    hilo = 'hi';
  } else {
    hilo = 'hi';
  }
};
var num = parseFloat($('#balance').html());
bconfig.startbal = num;
bconfig.want = num + 0.00000030;
bconfig.autoexit = num - 0.00000420;
rollDice();

5. Then right click anywhere in the inside the MULTIPLY BTC page and then select "Inspect" or press ctrl+shift+j in your keyboard
6. There is something that pops up in your screen, dont worry, it will not bite. Click CONSOLE tab on that pop up screen and then paste the code that you've copied above and it will start betting

NOTE: If the bet is more than 0.0002200 and you loose the bet, the code will automatically stop and you will need to run again the script by refreshing the page and paste again the code.

Happy Earnings.
