        <span>Before you proceed, please understand that the Lightning Network is still considered experimental and is under active development.</span>
    </p>
    <p><strong>Do not add money that you can't afford to lose - there's a high risk of loss of funds.</strong></p>
    <p class="mb-2">Take time to familiarize yourself with the risks, some of which are:</p>
    <ul class="mb-4">
        <li>Most BTCPay Server deployments run on a pruned node which, while working, is not officially supported by lightning network implementations.</li>
        <li>
            Lightning keys are NOT automatically backed up by BTCPay Server. Your keys are in a hot-wallet. This means:
            <ul>
                <li>If you erase your BTCPay Server virtual machine: you lose all the funds.</li>
                <li>If your server gets hacked: a hacker can take all of your funds by accessing your keys.</li>
                <li>If there is a bug in a lightning network implementation: you could lose all the funds.</li>
            </ul>
        </li>
    </ul>
    <hr>
    <p class="mb-2">To proceed, please ensure that:</p>
    <ul>
        <li>You accept being #reckless and being the sole responsible party for any loss of funds.</li>
        <li>You agree to keep on your lightning node only what you can afford to lose.</li>
    </ul>
