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.
