I would say that almost all those people who sold out their altcoins for buying bitcoins to get free S2X coins would have sold their bitcoins to once again buy cheap altcoins.That's the reason for the price fall.I think that we are already near the bottom price.

So,you could just wait until the price reaches $6500 and then buy without further delay as i hope that bitcoin price would once again start to recover after that.If you delay more than that,then you may miss the train.
