// SQUID Game (SQUID) is originally a meme coin on Binance Smart Chain.
// It is now following in the footsteps of $BTC, $DOGE, and $SHIB. A token with no founder team, and fully driven by the communities.
// A passionate and committed team of community volunteers has breathed new life into the SQUID project, rescuing it from its unfortunate past and steering it towards a promising future. They're launching the expansion of SQUID Token on the Ethereum Mainnet, and it's packed with some seriously impressive features.
// This is a genuine resurrection and a redemption story like no other!

// Here at ETH, SQUID Game Token is a community driven, fair launched DeFi Token, governed by SQUID DAO Contract.
// SQUID Game spirit is to create a community that is united and strong, bonded by the will to survive and win.
// With SQUID Frontman advocating for fairness, transparency, and sharing wealth to the masses, SQUID Game Token is a token that is built to last.
