# Buyback & Burn

<figure><img src="/files/XhDlT2fuHdaJmnNn84GS" alt=""><figcaption></figcaption></figure>

Gyrowin has two types of combination functions for **Buyback**, **Burn** and **Reward**.

## 1. Buyback -> Burn

There are many unwelcome swap transactions such as front/backrun bots that cause panic selling and holders to lose their interest. Gyrowin watches closely the unhealthy chart and we cure it with buyback.

{% hint style="info" %}
The same amount of burn will be immediately executed after the buyback at the single transaction.
{% endhint %}

## 2. Buyback -> Burn & Reward

Every lottery has a 5% reward of the total prize for buyback.

Once the buyback happens, the amount will be burnt and rewarded for the Money plant respectively.

Burn can not be happened when total supply reach under 2 billion tokens.
