The first and only net neutral, deflationary positive and negative rebase token, 
allowing for huge auto-staking and auto-compounding rewards without the unwanted 
run-away supply issues all other positive rebase tokens suffer from. Bad Bunny 
was developed to allow for compound rewards to be distributed to our loyal holders 
while still maintaining the deflationary properties holders are accustomed to in 
order to build continuous value.
