Yes, that's right. Altcoin is influenced by Bitcoin. It seems to me that prices for Altcoins are growing only when the price of Bitcoins is stabilized.
Yes I agree, as we know that bitcoin marketcap when it reaches more than 53%, bitcoin becomes the standard price for altcoins because most of it is trading with fiat, when the price of bitcoin goes up then the price of altcoins rises and vice versa.
