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.
