Bitcoin dominance increase because most altcoin drop more than 90%. Bitcoin dominance more than 50% from market cap value and i think its not good for altcoin. If more people more interesting to invest in bitcoin, altcoin could drop more and i think bitcoin dominance should be at 30% and that will be good for cryptomarket
How Altcoin will go up if Bitcoin is getting worse and worse every day and no good points are seen. All will feel the same if the queen of all types of coins has decreased. Nothing can be done at this time by holding for a long time.
