I`m afraid that you will be disappointed if you wait for December to be clear on Eth price. They announced upgrade for January, when that happens eth will be in turbulent times, its something that every hardfork causes. We will see more volatility in that period, price can move in any direction. Consequences of the hardfork, it will take time for everything to be checked and rechecked, for upgrade to be accepted. What will happen with ethereum will have a big impact, don`t think anything else, and we need to give couple months for everything to settle down, after that we will see where eth is and where its going, until that we can just hope for the best.
even the Ethereum 2.0 are launched in the next year and maybe Bitcoin are make movement in the end of year, of course Ethereum will adjust the price on market following bitcoin uptrend like few year ago after bitcoin enter bullish another altcoin are affected, especially with Ethereum
