# How to maximize your bbBNC yield?
{% hint style="success" %}
The principle of maximizing bbBNC returns is simple:
The larger **your proportion of bbBNC holdings is in the total supply**, the **more protocol revenue sharing** you will receive, thus increasing your APY.
{% endhint %}
There are three ways to maximize your bbBNC returns
* Extend BNC & vBNC locking
* Deposit vToken & vDOT-BNC LP for an additional boosting
* **DO NOT** unlock your position too early
{% stepper %}
{% step %}
### Extend your BNC & vBNC locking is the most efficient way to amplify your bbBNC APY.
If you have an existing bbBNC position, go to "manage" and click "Extend" to view the effects of extending.
As shown in the table below, the amount of bbBNC received correlates directly with the lock-up duration. Locking one vBNC for four years (with locked BNC automatically converting to bbBNC at the vBNC exchange rate) provides the maximum bbBNC amount. However, a 3-month lock-up would require about 3.3 times more principal to achieve the same results as a four-year lock.
| Locking Duration (per vBNC) | bbBNC received |
| --------------------------- | -------------- |
| 3 months | 0.296875 |
| 6 months | 0.3424 |
| 1 year | 0.4375 |
| 4 years | 1 |

### Boost your bbBNC value with LP & vTokens
{% hint style="success" %}
In general, you can deposit vToken or BNC-vDOT LP to amplify your existing bbBNC amount, similar to a power-up buff. However, this boost will disappear when you withdraw your staked assets.
{% endhint %}
{% hint style="info" %}
Depositing your vToken is separate from joining farming pools. Instead, depositing vToken increases your bbBNC amount, which in turn enhances your farming yield. Check how bbBNC boosts on Farming page at [here](https://app.bifrost.io/farming?network=polkadot) and discover those pools tagged with "bbBNC boost pool".
{% endhint %}
Two key indicators determine the boost weight:
* The proportion of staked LP & vToken in total supply
* The proportion of staked LP & vToken in total staked amount
To achieve a higher weight, both ratios need to reach certain levels. The following example will demonstrate different weight scenarios for users A, B, and C:
In this example, although User B has deposited a considerable amount of vTokens, their boost coefficient has not reached the maximum value due to the large total supply of vTokens. As for Users A and C, who have locked different amounts of LP, their boost coefficients vary significantly with changes in locked amounts due to the smaller total LP supply
{% endstep %}
{% step %}
### DO NOT unlock your position too early
{% hint style="danger" %}
Early unlocking will not only result in the loss of existing bbBNC but also incur corresponding penalties. This approach is highly unfavorable for maximizing returns.
