# Coin control

When you receive Bitcoin (or several other coins), your balance isn't one big pool — it's a collection of individual "outputs," like separate bills in a wallet. Coin control lets you see those outputs and choose which ones a transaction spends. That matters for privacy: it keeps coins you'd rather not link together — say, a KYC exchange withdrawal and a private payment — from being spent in the same transaction.

Coin control is available for Bitcoin, Litecoin, Bitcoin Cash, Dogecoin, Monero, and Decred wallets.

## View your coins

{% stepper %}
{% step %}

### Open Coin Control

Open `Settings` from the top right of the home screen, tap `Privacy`, then `Coin Control`.

{% endstep %}

{% step %}

### Review your outputs

Each row is one output: its amount and the address it was received on. Tap an output to see its details.

{% endstep %}

{% step %}

### Label or freeze an output

The details screen shows the output's amount, transaction ID, and address. Add a note so you remember where it came from ("exchange withdrawal", "paid by Alice"), or flip the `Freeze` toggle to stop it from being spent.

{% endstep %}

{% step %}

### Frozen coins stay put

Frozen outputs move under a `Frozen` header and are never spent — they show up in your unavailable balance until you unfreeze them. Freezing is persistent across all transactions until you change it.

{% endstep %}
{% endstepper %}

## Choosing coins for a single transaction

You don't have to freeze coins to control one payment: the Send and Swap screens also let you filter which outputs that one transaction may use, without changing anything permanently. Look for `Coin Control` under the Send screen's `Advanced Settings`.

{% hint style="info" %}
If your available balance looks lower than expected, check here first — frozen outputs are excluded from what you can spend. See [Why is my Available Balance 0?](https://docs.cakewallet.com/faq/zero-balance) for other causes.
{% endhint %}

## 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.cakewallet.com/features/advanced/coin-control.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.
