I do not think on chain fees under 10 sats will happen very much anymore.
This 2024 1/2 ing will be more like a 35-40% ing. not a 1/2 ing.
as there are unstoppable methods large farms can do to make their profits higher.
you can not stop a 30% pool from down clocking and slowing blocks to clog the mempool then once the mempool is clogged bump hash up to grab high fee blocks... We should see real evidence of this happening after this 1/2 ing
We just saw 8 sat vB about 2 weeks ago.
I do not think miner will refuse low fee rate transactions and mine empty blocks.
If some pools decide to do so, there will always be pools That will clear the mempool and mine full blocks, no matter the fee rate.
For now, there are 130000 transactions in the mempool. But that is quite unusual and ordinals and the bull market won't last forever..
