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.
