	<h2>Deposit credits</h2>
	<p>
		To deposit funds on your pixeldrain account please contact
		<a href="mailto:sales@pixeldrain.com">sales@pixeldrain.com</a>. We will
		prepare an invoice for you. We accept wire transfers and PayPal. As we
		are located in the Netherlands SEPA payments should be free and instant.
	</p>
	<p>
		Pixeldrain credits can be used for our prepaid plans, which are
		different from the Patreon plans. Because preparing invoices requires
		some manual labour we only accept deposits of €100 or more. The prepaid
		plans are meant for people who require a lot of bandwidth or storage.
		Paying only for what you use means you can save money compared to a
		fixed monthly price.
	</p>
	<h3>Crypto payments</h3>
	<p>
		Alternatively you can use Bitcoin, Lightning network (<a
		href="https://btcpay.pixeldrain.com/embed/uS2mbWjXUuaAqMh8XLjkjwi8oehFuxeBZxekMxv68LN/BTC/ln"
		target="_blank">node info</a>) and Dogecoin to deposit credits on your
		pixeldrain account. 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.
	</p>
