# How to participate at Presale

How to Buy a Launchpad presale on ONI: Youtube video soon

1. From home page, access "Launchpads" => "Launchpad list" or the following link to all launchpads: <https://oni.exchange/launchpads>
2. You can filter the presale statuses by selecting from the "Filter By" list. You only can buy a presale with the “Inprogress” status.
3. Hover over a presale you want and click on “View Pool”.
4. After clicking on “View Pool”, you can see all the information related to that presale. You should check everything carefully before buying.
5. To buy the presale, insert the amount of BNB (or USDT, USDC, ETH,... depending on the pool) that you want to use to buy in the “Amount” section. The corresponding amount of presale tokens will be calculated automatically below the BNB amount. Finally, click on the “Buy” button.
6. MetaMask will now ask you to confirm the transaction. It will also show you the fee that you are required to pay for that transaction. If you agree, then click on the “Confirm” button to finish the process.
7. After buying, you will see the changes in the “Amount” and “You purchased” sections. For this pool, the maximum buy is 20,000 USDT, I purchased 10,000 USDT so the amount has changed to 10,000 USDT (= 20,000 - 10,000).

## 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:

```
GET https://oni.gitbook.io/oni.exchange/investing/how-to-participate-at-presale.md?ask=<question>&goal=<endgoal>
```

`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.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
