# Boost thẻ NFT (thẻ bonus)

Mỗi thẻ có thể được boost tối đa 5 lần để cải thiện thuộc tính Earning. Mỗi lần boost sẽ tiêu tốn 200 NEXT để tăng mức earning thêm 2 đơn vị, mỗi lần boost phải cách nhau tối thiểu 48 giờ.

| 5             | 200                  | 2                     | 48hr              |

Chỉ số earning hiện tại của thẻ NFT sẽ quyết định mức tăng phần trăm phần thưởng sau mỗi lần bạn boost. Nguyên tắc cơ bản là thẻ có earning càng cao thì mức tăng sẽ ít lại vì bạn đã có thể kiếm rất nhiều NEXT với mức earning cao của thẻ mình rồi.

## 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://docs.shopnext.io/vietnamese/whitepaper/cach-tham-gia/the-nft-the-bonus-la-gi/boost-the-nft-the-bonus.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.
