**Understanding Buy Tax**

* Pay 0% in taxes as a buyer and receive 2% additional tokens instantly.\
  Example: buy 1,000 tokens and receive 1,020 tokens in return.

**Understanding Sell Tax**

* 2% Sell tax → Converts into BNB and automatically sends to a contract which buys back $UltronAI tokens and burns it as soon as 5 BNB accumulated. \
  *(Buy back trigger amount can be adjusted based on volume.)*\
  \ <mark style="color:red;">**The purpose of this contract is to ensure that during sells it will build up the buyback wallet and then push the chart back up.**</mark><br>

**NOTE:**\
**This contract is also multi-functional such that the buy tax can also be adjusted to:**\
\
2% buy (Converts into BNB to auto-buyback and burn $ULTRONAI)\
2% instant refund\
0% sell\
\
So during uptrends or marketing pushes, it can build up on buys and trigger buybacks at higher prices to keep the momentum.<br>
