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.
