Do they really? I often encounter this statement. And i have no idea as to why. This past few days, bitcoin is on the rise and most certainly than not altcoin's price surely follows. I am not saying this is bad but altcoins have very little in common with bitcoin. And they are certainly not carbon copies of bitcoin either. Why the heck is their price so closely connected despite being so fundamentally different?
In my own opinion bitcoin as king of altcoins are not possible follow the price of altcoins into bitcoin price value if the bitcoin price goes dump of course altcoin price goes lower value but if the bitcoin go uprise the altcoins price will follow to increase in their king.
