The dominance is still staying above 65%, despite some late fight back from the alts. The trends indicate that the market share of Bitcoin will continue to increase, reaching 70% or more by the end of this year. And it will increase further next year, as a result of the upcoming block reward halving. Right now I don't see a good future for any of the alts.
That makes sense because bitcoin will be the ultimate reason for people to buy crypto currencies. Investors are also smart not touching altcoins for now because of the great effect that the halving will give to bitcoin. I expect altcoins to go very quiet for now and its time for moon season is after a few months of the bitcoin halving.
