# FAQ

Answers to the questions we hear most often. For deeper background, see [Energy & Bandwidth](/concepts/energy-and-bandwidth.md) and the [Glossary](/concepts/glossary.md).

## Why is the price higher when buying with the bot than on the website?

There are two common explanations.

**Case 1 — Target address mismatch.** Double-check the **target address** in your order. Discrepancies in the target address can lead to price differences.

**Case 2 — Different matching strategy.** The bot and the website use different purchasing flows:

* On the **website**, you can set the lowest possible price - which means the order may not match 100%.
* On the **bot**, orders are always placed at the **`MEDIUM`** price to ensure every bot purchase matches 100%.

In most cases, the bot and website prices are the same. The bot's price is only higher than the website's when the system runs out of resources to match against.

If you want full control over price (and accept the chance of a partial fill), buy on the website. If you want a guaranteed 100% match, use the bot.

## What are TRON Energy and Bandwidth?

Energy and Bandwidth are the two resources every TRON transaction consumes. They are acquired by **locking (staking) TRX**, which generates these resources during the lock period. While your TRX is frozen, it cannot be traded, bought, or sold until it is unfrozen after a specified number of days.

* **Bandwidth** is granted as a reward for freezing TRX and is required for the byte size of a transaction.
* **Energy** is an exclusive TRON resource representing a unit of CPU consumption within the network. It can only be obtained by freezing TRX.

Both resources are essential for creating and executing smart contracts. See [Energy & Bandwidth](/concepts/energy-and-bandwidth.md) for full details.

## How do I get Energy?

There are three ways to obtain Energy.

### Method 1 - Burn TRX

If your account does not have enough Energy, TRX is **automatically burned** during a transfer to cover the Bandwidth and Energy the transfer requires. Compared with consuming staked Energy, burning TRX is **not cost-effective**.

### Method 2 - Freeze (stake) TRX

Open the TRON resource management interface (<https://tronscan.io/#/wallet/resources>), choose the resource type you want, and enter the amount of TRX to freeze.

The Energy you obtain is calculated as:

```
Energy obtained = (frozen TRX / total network frozen TRX) × total network Energy limit
```

This distributes the fixed network Energy evenly across all frozen TRX. Frozen TRX can be thawed and retrieved after **14 days**. Consider this method if you have a lot of idle TRX.

{% hint style="warning" %}
Staking locks your TRX for 14 days before it can be unfrozen and reclaimed. Plan accordingly if you need liquidity.
{% endhint %}

### Method 3 - Buy Energy on TronSave

Renting Energy through [TronSave](https://tronsave.io) saves on fees. You don't need to freeze a large amount of TRX or burn extra TRX, and you can save roughly **60–80%** of the handling fee.

See [Order Types](/concepts/order-types.md) and the [Quickstart](/getting-started/quickstart.md) to get started.
