It looks like bitcoin's dominance will continue, as the market focus is now on it, we can see after the FUD on bitcoin, buying on altcoins decreased as many prefer to buy bitcoin due to a decline, with hopes of an increase in the near future
This dominance thing doesn't really freak me because I don't see its point when China and some other countries are manipulating things and price keep dumping every week, altcoins included.
The best time I have seen the useful of this dominance is when we riding bullrun and then whales began to shift money frkm altcoins to bitcoin or from bitcoin to altcoins.
