https://t.me/BabySquawkCoin

The inspiration of the Baby Squawk token comes from the Squawk token created by one of the SHIB devs. The purpose of this token will be similar to any other
"Baby" version of a token: buying the original token (Squawk, in this case) and burning some of its supply. This will eliminate some supply of Squawk,
thus increasing all holders value of their tokens. In addition, we will aim to reach out to the dev who deployed the Squawk token in the hopes of setting up
an official partnership. Other marketing will happen regardless of the success of this partnership. The tokenomics of this coin are listed below:

Buy tax: 1% auto LP + 6% marketing = 7% total
Sell tax: 1% auto LP + 9% marketing = 10% total

50% marketing goes to buying and burning Squawk token, and 50% goes to marketing this coin.

Website and socials coming soon. With all that being said, welcome to Baby Squawk :)
