Everytime bitcoin crashes it's price eth will also be affected and declined badly once it happened.
That pretty shows the dominant of bitcoin controlling the entire market, and that includes ETH.
Probably there'll be possible minimal fall, but not to the point it could worsen it's scenario. We've expecting a lot of trending probabilities now, because it seems corrections already taken it over and will cover up the struggles of holders.
To make it simple, we should not look only at the dollar value because if we do, we might get confuse, look at the graph instead.
Thing is, ETH rises in value because BTC rises, and when it moves in the other direction, it follows, ETH has not rally yet independently, same with most alts.
