BITCOIN               
                                        
                                          
 BITCOIN IS  A CRYPTO COIN,  CRYPTO  HERE 
 MEANING "HIDDEN", BECAUSE  THIS MONEY IS 
  INVISIBLE, INTANGIBLE (YET STILL REAL)! 
 THIS  IS A SYMPTOM  OF IT ONLY LIVING ON 
 THE INTERNET -  IN FACT, IF YOU WERE  TO 
 REMOVE A BITCOIN FROM THE  MAINFRAME, IT 
     WOULD IMMEDIATELY DIE AND BECOME     
                WORTHLESS.                
                                          
 IT WORKS  LIKE  THIS: IF YOU  MAKE  YOUR 
 COMPUTER  CREATE  A LOT  OF  HEAT,  IT'S 
 REWARDED  WITH  BITCOIN, AS  A  TOKEN OF 
       GRATITUDE FROM TIME'S ARROW.       
                                          
 THEN EVERY OTHER COMPUTER  HAS TO SIGN A 
 DOCUMENT  STATING THAT  THOSE  COINS ARE 
 ACTUALLY  YOURS. YOU CAN  THEN SEND THEM 
 TO  OTHERS, GENERATING  A  NEW  DOCUMENT 
          FOR EVERYONE TO SIGN.           
                                          
 AND BECAUSE  YOU'RE KNEE DEEP  NOW,  YOU 
 HAVE   TO   SIGN  A  LOT  OF   DOCUMENTS 
 YOURSELF, AND  KEEP TRACK OF  WHO SIGNED 
 WHAT, AND  LOOK  FOR  FORGED SIGNATURES, 
 AND  PROBABLY  FORGE A  FEW  YOURSELF... 
                                          
 ALSO,   IN  THE  END  IT  DOESN'T  WORK.
