I`m afraid that you will be disappointed if you wait for December to be clear on Eth price.
Tbh, I won't be dissapointed. Since after many years in December Eth price was really volatile at that time and from what we have seen even they were doing hardfork and upgrade, the price weren't moving and it could be worse.
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.
That would be okay to wait, since I'm pretty sure in November we would not see any good thing happen.
