In 2019, the most famous version was hosted on Pastebin under the ID zUvL7xYp (now dead). A typical script header looked like:
// ==UserScript==
// @name FreeBitcoin Auto Roller 10k
// @namespace http://tampermonkey.net/
// @version 2.0
// @description Rolls 10,000 times on FreeBitcoin with captcha solving
// @author CryptoAnon2019
// @match https://freebitco.in/*
// @require https://code.jquery.com/jquery-3.4.1.min.js
// @grant GM_xmlhttpRequest
// ==/UserScript==
Inside the script, users had to edit these variables: freebitcoin roll 10000 script 2019 install
var total_rolls = 10000; // Number of rolls
var use_hi = true; // true = bet on HI (>49,500), false = bet on LO
var captcha_api_key = "YOUR_2CAPTCHA_KEY";
var roll_interval = 61000; // 61 seconds (to avoid hourly reset)
