Bitcoin can indeed have an impact on Altcoins especially in terms of price and I am aware of that. Having experienced several market corrections this year, Bitcoin prices fell and rose again as they are today. But for Ethereum, I don't think $6K will happen again until December. The opportunities I see will only be in the highest price range of $4.7K and that I can't really confirm is just an opportunity.
Getting past the $4K price would obviously be very possible for Ethereum because at the moment the price of Ethereum is already at $3,397 and obviously not too far from $4K so it has a chance to happen if conditions can be very stable from now on, because soon everyone will end of 2021
