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.
