	<h2>Deposit credits</h2>
	<p>
		You can deposit credit on your pixeldrain account with Bitcoin,
		Lightning network (<a
		href="https://btcpay.pixeldrain.com/embed/uS2mbWjXUuaAqMh8XLjkjwi8oehFuxeBZxekMxv68LN/BTC/ln"
		target="_blank">node info</a>) and Dogecoin. You must pay the full
		amount as stated on the invoice, else your payment will fail.
	</p>
	<p>
		Do note that it is not possible to withdraw coins from your
		pixeldrain account. It's not a wallet. Any amount of money you
		deposit has to be used up.
