/*
AGI wAIfu needs a Pepe, she’s the true $Pepe stan. 
You don’t need to hold $Pepe but if your wallet has it at the time of the wAIfu mint, 
then your wallet is whitelisted for both super rare and 
unique traits as well as WL the wallet for the Artificial General Intelligence platform beta. 
Due to AGIwAIfu’s fondness for $Pepe and team members actively contributing 
to the advancement of the redecision learning curve, AGI wAIfu is poised for growth and 
real advancement in digital life. 

Every $50 spent is a mint unless sold within 7 days. 
Top 200 holders at 1 million market cap receive some of the rarest wAIfu traits.
Top 100 holders at 2 million market cap receive additional vested tokens and 
are granted access to the AGI feedback portal to help realize the vision of 
Artificial General Intelligence for all Pepes and wAIfus.
