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.
