	<h2>Deposit credits</h2>
	<p>
		Pixeldrain credits can be used for our prepaid plans, which are
		different from the Patreon plans. With prepaid you only pay for what you
		use, at a rate of €4 per TB per month for storage and €2 per TB for data
		transfer.
	</p>
	<p>
		Use the form below to deposit credit on your pixeldrain account using
		Mollie. The minimum deposit is €10. <b>Mollie payments are currently
		only available in Europe</b>.
	</p>

	<MollieDeposit on:checkout={e => checkout("mollie", e.detail.amount, e.detail.country)}/>

	<h3>Crypto payments</h3>
	<p>
		Alternatively you can use Bitcoin, Lightning network (<a
		href="https://btcpay.pixeldrain.com/embed/uS2mbWjXUuaAqMh8XLjkjwi8oehFuxeBZxekMxv68LN/BTC/ln"
		target="_blank" rel="noreferrer">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>
