That's right, even though the other coins have the potential to rise at the moment but the authority is in bitcoin because their value has been dependent on up or down the value of bitcoin.
That's not the point, not all altcoins depend on the price of bitcoin. Even all altcoins have their own ways to experience price increases and price declines, I don't understand that I am someone who disagrees with people who always saying about altcoin price movements depending on bitcoin. Bitcoin has many investors, even most of them dominated the cryptocurrency market, but maybe you often see when the price of bitcoin decreases and you can see the altcoin price must be there which always increases, this means that what people say is not entirely true.
