On AliExpress you&rsquo;ll find clones with a bigger <strong>3.5&quot; (480×320) screen</strong>, from sellers such as YYSlupping. The hardware is nice. The firmware is the problem.</p> <h2 id="the-problem-closed-firmware-on-an-open-source-miner">The problem: closed firmware on an open-source miner</h2> <p>These clones ship with <strong>pre-installed firmware whose source code isn&rsquo;t published</strong>. A miner has your pool login, your payout address and all your hashrate, and with closed firmware there&rsquo;s no way to check what it does with them.</p>
