I don’t know the reason for the surge, it could have also been manipulated, but I see that there are some coins that also pulled up along with bitcoin and I don’t want  to believe yet that this is the beginning of altcoins season that we have been waiting for, we will still wait for another few days to really confirm if this is indeed the bull run that we have been waiting, but for what I think, I think bitcoin dominance will still continue for the rest of this year before altcoins makes a head for their own bull run, and that will hopefully be by the time the halving of bitcoin starts next year. Altcoins are actually due for their own bull run if not for the scam projects that came to discourage everyone about ICO.
