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.
