# Payment and top-up in cryptocurrency
You can pay for the issuance of a Wanttoopay card using cryptocurrency through the Cryptomus payment service. The following coins are supported: USDT, USDC, TON, BTC, BNB, ETH — choose any that is available in your wallet or on the exchange.

Frequently Asked Questions:
What should I do if the money was deducted, but the status on Cryptomus was not updated?
Check:
* You entered the exact payment amount
* You selected the correct network
If everything is correct, just wait: the status is usually updated within 5–10 minutes.
If that does not happen, write to [@WantToPaySupportBot](https://telegram.me/WantToPaySupportBot)
Why is the final amount higher than the card denomination?
The amount includes:
* card denomination
* Cryptomus fee
All fees are shown before confirmation
What should I do if the payment period on Cryptomus has expired?
Create the order again in the mini-app and follow the instructions. Old links become invalid after the time expires.
I encountered an error while topping up

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
