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.
