Don't claim I don't understand it when I was clearly talking about the economics of bitcoin. Also, if you are paying to mine currencies that don't have an exchange value yet, you are just speculating. The mining isn't profitable at that point because the currency has no value. It's just as likely that you chose to mine a dud. It's exactly the same thing as opening a copper mine at a loss and hoarding the concentrate hoping that it will gain value.
