  Volume Feeder for Proof of Community (POC)
  KujiraBro Loves Ethereum but he Loves POC tokens more. 
  He will Buy and HODL PoC tokens and spread his Divies. 
  However when he has a bit too much POC he will sell for the sake of volatility. 
  All his divies go back into buying more POC and Spreading more Divies. 

  KujiraBro is Proof of Community's best Buddy.
