The BTC dominance is always in a state of flux. I for one cant see BTC's dominance being reversed permanently. We see the dominance go in waves. I think alts have been very quiet over the last few months and the only progress that we saw come from bitcoin however as we have all seen, we are having a mini alt season. This I don't think is new money, Its more likely to be money that has been waiting on the sideline for the last few weeks waiting for any sign of strength to jump back into the alts. We are seeing a pattern of bitcoin jumping and then alts catch up and following btcs recent rise of 30% from the lows, alts again have followed suit so I think people are beginning to clock onto this trend. Long term I don't think btcs dominance is going to drop
