# Pay with crypto (NOWPayments)

> Buy Premium / Verified / Donate / Custom-badge slots with BTC, ETH, USDC, and 100+ other coins.

Crypto payments use **NOWPayments**. The whole flow stays **on biolovers.site** — pick a coin, we show you an address + amount + QR code, you send the funds, our page polls until your payment confirms.

## What you can buy

* **Premium** (\$6.99 lifetime) — see [What Premium unlocks](/premium/what-premium-unlocks)
* **Verified** (\$19.99 lifetime) — see [Verified](/premium/verified)
* **Donations** ($1.99 – $1,000) — see [Donations](/premium/donations)
* **Custom badge slots** (\$4.99/slot, volume discount) — see [Custom badges](/badges/custom-badges)

## How to pay

1. Go to the checkout page (e.g. <a href="https://biolovers.site/premium" target="_blank" rel="noopener">/premium</a>).
2. Tap **Purchase**.
3. In the popup, pick **Cryptocurrency**.
4. Choose your coin from the searchable picker.
5. Accept **Terms** + **Refund policy**.
6. Tap **Purchase — \$X.XX**.
7. The page swaps to a panel with:
   * Pay-to **address** (long string)
   * Exact **amount** in that coin (quoted from the USD price at the moment of purchase)
   * **QR code** for mobile wallets
   * **Status badge** (waiting / confirming / paid)
8. Send the **exact amount** from your wallet.
9. The page polls every few seconds. When NOWPayments reports `finished`, your account is upgraded.

## Important

* **Send the exact amount.** Underpaying = no upgrade. The amount is quoted at purchase and can drift if the network is slow — see [Refunds](/premium/refunds) for what we can do if a payment lands late.
* **Don't close the page** until the status is `finished` — your status panel will tell you when it's safe.
* **Confirmation time** depends on the coin. BTC \~30 minutes; USDT (TRC20) \~1 minute; ETH \~5 minutes.
* If your coin has a **minimum amount** higher than the order total, the API will refuse — use a different coin (USDT/USDC TRC20 usually have low minimums).

## Receipts

We send a branded Biolovers receipt email once payment confirms. NOWPayments do **not** send their own — only the on-page status reflects their side.

You **must have a verified email** to checkout (the API enforces this — see [Email](/account/email)).

## Common questions

<AccordionGroup>
  <Accordion title="My payment is stuck on 'waiting'">
    NOWPayments shows `confirming` once the network sees your transaction (usually after 1 confirmation). It then needs the coin's full confirmation count. Bitcoin can take 30+ minutes. Don't resend.
  </Accordion>

  <Accordion title="I sent the wrong amount">
    Underpayments aren't auto-credited. Open a ticket through our <a href="https://biolovers.site/contact" target="_blank" rel="noopener">contact form</a> with the transaction hash + the order ID — the team can usually credit you manually.
  </Accordion>

  <Accordion title="Can I get a refund?">
    See [Refunds](/premium/refunds). Crypto transactions are typically irreversible once confirmed; refunds are issued at the conversion rate at the time we send them, in a coin we support, with network fees not reimbursed.
  </Accordion>

  <Accordion title="Why does the page say 'crypto unavailable for this amount'?">
    The provider's minimum for that coin is higher than your order. Pick a different coin (USDC / USDT usually have low minimums).
  </Accordion>

  <Accordion title="Did I miss the receipt email?">
    Crypto receipts come from us, not NOWPayments. Check spam, then your account email is the right address — verify it on the [Email](/account/email) panel.
