The corresponding amount of presale tokens will be calculated automatically below the BNB amount. Finally, click on the “Buy” button. 6. MetaMask will now ask you to confirm the transaction.

For this pool, the maximum buy is 20,000 USDT, I purchased 10,000 USDT so the amount has changed to 10,000 USDT (= 20,000 - 10,000). --- # Agent Instructions: 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.
