Oh god... the time machine again.. When I first joined this forum three years back, there were a lot of such threads. Everyone needs to understand that time machine is a piece of fiction and it will never materialize. And even if a time machine is available, why go back to 2013? Why can't you go back to 2009 and mine all those coins? And why don't you go back to the 1990s, before the dot com boom? The list may go on endlessly.
