## 2. 設置BTC默認地址格式

## 3. 設置貨幣最小回調金額

於最小回調金額找到你想設置的貨幣，這裡只會顯示的錢包已加入的貨幣。選擇後點擊編輯便會有數字輸入框，用戶可設置當充值金額低於一個數值時不會觸發回調而防止充值騷擾或粉塵攻擊。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://support.cregis.com/cregis-wallet-guide/zh-tw/deveoper-and-payment-engine/manual/hui-diao-she-zhi.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
