It's evident from the recent upsurge in bitcoin price that the altcoins also followed along the line. That's to say that the bull, if and when it comes with bitcoin, will also be for altcoins. Altcoins shouldn't be left out.
The theory will stand if that happens this time, right now what we are seeing is that the market is moving higher when ever the price of bitcoin is moving higher but that does not mean that when there is a huge rally in bitcoin that the entire alt coin market will rally along with it, we have not seen that market situation in the past and i am not expecting that to happen this time around, i might expect a rally in top alt coins once a huge rally in bitcoin subsides and not before that.
