/*
Type Type Type. Pay Pay Pay.
The little dev created his memecoin. He was a happy little dev. 
His project was full of good things for buyers and jeets. 
There were all kinds of goodies for the investors.
Callers with big followings, Trending positions, buyback & burns, and even a raid army. 
The little dev gave every kind of marketing that buyers or jeets could want.

The little dev said, "I think I can make this token go the the moon. 
I think I can I think I can." Then the little dev began to work. He worked and he jerked.
He jerked and he worked. Type Type Type, Pay Pay Pay went the little dev. 
"I think I can I think I can," he said. Slowly, slowly the memecoin started to pump. 
The buyers and jeets began to smile and clap. Type Type, Pay Pay. 
Up to the top of the volume charts went the Little Dev. 
And all the time he kept saying, "I think I can, I think I can, I think I can..." Up, up, up.
 The little dev's token's chart climbed and climbed. 
 At last his token reached the top of the charts, at 50 million marketcap.
Down below lay the community. "Hurray! Hurray!" cried the buyers and jeets. 
"The investors will be so happy", said dev's mod team. 
"All because you helped us, Little Dev." 
The Little Dev just smiled.
