The real bitcoin is the one that was released in 2009 xD after that it changed and evolved and what we have now is not bitcoin, it's something else, something that adapted and evolved... Just like any species, us for example, we started as apes and evolved into homo sapiens sapiens, along the way we had many different forks, the one that survived, evolved and adapted is us, same thing will happen to Bitcoin, the free-market will choose a winner which isn't bitcoin but a more evolved version of it... a bitcoin sapiens sapiens!
