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.
