Martingale BitCoin betting bot for Freebitco.in

This script is based on the martingale system of betting on a hi/lo game on freebitco.in.  You must have at least 100000 satoshi in your account.

What is the martingale system?

This script doubles down on the initial bet until you win.  Hence the reason you need 100000 satoshi to run the automated bot to play without losing your shirt in under a minute.  The script will start it's bet at .000000001, if it loses, it doubles the bet to .000000002.  If it loses, it doubles the bet to .000000004 and will continue to do so until it wins .000000001 satoshi.  Then the script resets the bet to .000000001 and starts the process all over again.

While it's not a lot of satoshi to win (or lose), it is fun to play with and see how a Gambling bot can be made to do things on the web using Javascript.  Otherwise the same process can run manually and is a popular method with the online gamblers that play the dice game.


The script is in javascript and runs in both chrome and firefox, if you don't have them the links will bring you to the download sites.  Once it's downloaded and installed open the javascript console.

To open the javascript console hit CTRL-Shift-I:


Cut and paste code below into the javascript console and hit enter:

var startValue = '0.00000001', // Don't lower the decimal point more than 4x of current balance
    stopPercentage = 0.08, // In % of total BTC upper right hand corner, forces the script to not make dumb wagers
    maxWait = 777, // In milliseconds
    stopped = false, // debugging, change to true to test varible changes
    stopBefore = 1; // In minutes for timer

var $loButton = $('#double_your_btc_bet_lo_button'),
        $hiButton = $('#double_your_btc_bet_hi_button');

function multiply(){
    var current = $('#double_your_btc_stake').val();
    var multiply = (current * 2).toFixed(8);
    $('#double_your_btc_stake').val(multiply);
}

function getRandomWait(){
    var wait = Math.floor(Math.random() * maxWait ) + 100;

    console.log('Waiting for ' + wait + 'ms before next bet.');

    return wait ;
