* O.P.P is built to stabilize the token launch for the first 24 hours.
* It protects holders from dumps, they even benefit from them!
* Holders will be rewarded with $OPTIMUS tokens, while paperhands get Rekt and boost the liquidity. 

* Totalsupply 	  (100%):	15.000.000.000
* Max wallet		(2%):	   300.000.000
* Max transaction	(1%):      150.000.000 
* Liquidity will be locked for 30 Days (will be extended)

* O.P.P explained (READ THIS CAREFULLY):

* Sell within  2 hours : 32% burn (16% Back to the Liquidity Pool, 8% Redistributed to Holders, 8% Marketing) 
* Sell within  4 hours : 28% burn (14% Back to the Liquidity Pool, 7% Redistributed to Holders, 7% Marketing) 
* Sell within  8 hours : 24% burn (12% Back to the Liquidity Pool, 6% Redistributed to Holders, 6% Marketing) 
* Sell within 16 hours : 20% burn (10% Back to the Liquidity Pool, 5% Redistributed to Holders, 5% Marketing) 
* Sell within 20 hours : 16% burn ( 8% Back to the Liquidity Pool, 4% Redistributed to Holders, 4% Marketing) 
* Sell within 24 hours : 12% burn ( 6% Back to the Liquidity Pool, 3% Redistributed to Holders, 3% Marketing) 
* Standard burn:  8% burn ( 4% Back to the Liquidity Pool, 2% Redistributed to Holders, 2% Marketing) 

* After 24 hours the normal 8% sell tax is in effect
