It will not get 5k so easy ... There too many pools that will dumb ETH to stay around 2k. (Flexpool is doing that for example right now)
So 2k with EIP-1559 say goodbye to your profits.
Imagine Sparkpool to start dumbing their ETH ...
They have ETH 2.0 on the plans for the next year so they want cut profits from us and go into whales.
My 2 cents
My english is low. I don't understand what "to dumb ETH" means.
If I guess, you think some pools sell to keep ETH under 2k$.
I am sure they sell because they think that is the best yield. No conspiracy against ETH.
