Bitcoin is not yet getting in a serious crash, not in the future and not gong to drop at $6000. But if ever there is a crash in bitcoin, altcoin gain, it how the market works, investors shift their funds from bitcoin to altcoin to leverage their lost because of the crash. That's how I will do if bitcoin goes down hard.

However, there's also instance that even if bitcoin crash, the price of altcoin doesn't move that much and actually it also take a dip. So I conclude that its really hard to predict their movement and those correlation as somewhat moot point for me. That's why this crypto market is very different from any market that we have saw or experienced. Hard to see their correlation. So its better not to think of it, just buy altcoins in dip, don't make things complicated.
