I would imagine the large numbers of new people to crypto who are involved with Ethereum has more to do with pre-christmas price drops.
Most of the cash purchases for ETH have dwindled in the run into Christmas - because these people have switched their spending to Xmas priorities (gifts and family expenditures).
This tends to effect most crypto's big in the Western spheres and Eastern spheres.
After Xmas ETH price will pick up again

Then, there is POS implementation at end of Feb or beginning of March.
It should be remembered: Proof-Of-Work System does need to raise a lot of fresh cash from new purchases.
When Ethereum goes to Proof-Of-Stake, it will no longer need to raise lots of fresh cash from purchases.
