WELCOME TO A HUNTER’S DINNER: QUACK
The mystery continues as the hottest and most secretive token to ever hit the ETH network has spawned a new community-driven undertaking that aims to follow the footsteps of its predecessor. QUACK is not a Hunter’s Dream. It is a Trader’s Paradise where he controls the destiny of the vessel that ferries his riches. Tonight, you will be feasting!
TOKENOMICS:
Supply: 6,666,666,666 tokens
0 TAXES
No dev wallet / airdrops
3% max TRX, 3% max wallet
