# BNA Extraction

You can extract a total of 3 BNAs from a BeerGang in its lifetime.

The BNA extraction period takes 3 days per BNA,\
\
Once the extraction is completed, the BeerGang can no longer extract BNA. Since BNA is limited and possesses the unique attributes of BeerGang, caution must be taken in its extraction and use.

* Extraction Method and Required Items:
  * By staking 1 BeerGang NFT for 3 days, you can extract 1 BNA.
  * For each BeerGang NFT, a total of 3 BNA can be extracted.
  * A BeerGang NFT from which 3 BNA have been extracted can no longer extract any BNA.
  * Genesis BeerGang NFT cannot extract BNA.

* Considerations When Extracting BNA:
  * When you start extracting BNA, your respective BeerGang NFT will be moved to the staking wallet of the BrewingLab system.
  * Once the BNA extraction is completed, both your BeerGang NFT and the extracted BNA NFT will be sent to your DOSI wallet.
  * A BeerGang NFT that has completed all 3 BNA extractions can't extract any more BNA, even if it is resold C2C in the DOSI market.
  * BeerGang NFTs from which BNA is being extracted are all transparently recorded as transactions on the LINE blockchain, and you can also check this information in the My Page section of the BrewingLab service.
  * Don't be alarmed if the BeerGang NFT being extracted isn't in your wallet during the extraction process! All transactions are stored as transactions on the LINE blockchain. They are safely stored in the BrewingLab system's staking wallet during the extraction process, and once completed, they will be settled accordingly and sent to the user's wallet.
