/**

While we love to indulge in accumulating higher orders of bags at every step of the way, storytelling is the most important aspect of everything that we do. It is the connective tissue that binds all of our ideas, concepts and philosophies together.

Bags Bro is such a crypto project combining Meme, Story-telling and Defi utilities. The $BGBO tokens will be set as the native utility tokens which could be burned to mint Bro NFTs and unlock their Defi properties. Visit the website for more detailed information.

We view this project itself as an unfolding of a great story. There will be significant plot twists and turns as we reveal the destiny for all citizens of the great BAGMI Nations.

Our BagBerry phone will be fully operational after token launch. Now you could just press that green "dial" button to see how it works. Better to turn on the sound there!

100m $BGBO: 0 Tax Tokens
