Ethereum will surely go to reach a new ATH before year end, if Bitcoin will not going to fall down ethereum will follow. I believe that crypto is going be more bullish before the year end. The amazing hard fork and the acceptance of bitcoin as payment in more company's can maybe have an effect of the current price.
Though Transaction fee has not come down on Ethereum as yet but team is working on it to bring it down to reasonable level but after the upgrade Ethereum are countnousaly being burnt which mean less supply in the market which will ultimately push it to new ATH . It has already gained $1000 after the successful implementation of upgrade project but it has not shown its real colour. My expectation of Ethereum Price is between 8 to 10K before the end of 2021.
