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.
