/**
Inter-Kongz Capital: $IKC

-Whose Kongz is that? I think I know.
Its owner is quite happy though.
Full of joy like a vivid rainbow,
I watch him laugh. I cry hello.

He gives his Kongz a shake,
And laughs until her belly aches.
The only other sound's the break,
Of distant waves and birds awake.

The Kongz is Cyber, and deep,
But he has promises to keep,
After cake and lots of sleep.
Sweet dreams come to him cheap.

-Custom contract imporvement from CyberKongz community. 
-We hope to bring benefit of DeFi 3.0 cross-chain yield generation to $IKC holders.
-You buy on Ethereum, we carefully ape on multiple chains and return the profits to $IKC holders.

Tokenomics:
10% of tax goes to existing holders.
10% of tax goes into cross-chain farming to add to the treasury and buy back IKC tokens.

Roar.
