Yesterday, you met the Myōbu, today the saga continues. 

Inari Ōkami is also known as the god of general prosperity and worldly success. Ōkami is generless and is 
sometimes seen apearing as a beautiful woman and other times as a handsome man. The Myobu,
celestial foxes, serve as messengers for Ōkami.

Again, rewarding holders and discouraging dumping.

1. Buy limit and cooldown timer on buys to make sure no automated bots have a chance to snipe big portions of the pool.
2. No Team & Marketing wallet. 100% of the tokens will come on the market for trade. 
3. No presale wallets that can dump on the community. 

You learned how this works now time to do it bigger.

Cool Down Times:
1. First Sell - 2 hours
2. Second Sell - 4 hours
3. Third Sell - 16 hours
4. Fourth Sell - 48 hours

Token Information
1. 1,000,000,000,000 Total Supply
3. Developer provides LP
4. Fair launch for everyone! 
5. 0,2% transaction limit on launch
6. Buy limit lifted after launch
7. Sells limited to 3% of the Liquidity Pool, <2.9% price impact 
8. Sell cooldown increases on consecutive sells, 4 sells within a 24 hours period are allowed
9. 2% redistribution to holders on all buys
10. 7% redistribution to holders on the first sell, increases 2x, 3x, 4x on consecutive sells
11. Redistribution actually works!
12. 8% developer fee split within the team

Experiment #2
- disclaimer: token is worthless and is a meme coin with no utility
