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.
