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.
