Kongz Brain Capital DAO: $KBCD
- Deflationary DeFi-as-a-Service (DaaS) Token, with 65% supply burned to 0x0dEaD
- Our Kongz advisors will bootstrap the investments in our initial phase. We invest on multiple chains and return the profits to $KBCD holders.

Tokenomics:
- Buy Tax / Sell Tax: 14%
    - 5% of each buy goes to ETH reflections
    - 5% of each sell to treasury wallet
    - 4% to the liquidity pool.
