BUT if more and more miners join, doesn't that also mean that more and more users will also use sub 1 sat fee transactions which would make the miners' revenue from fees also go down?
¯\_(ツ)_/¯
The point is that bitcoin price is already way too high.
1 sat /vB is already a lot of money. 10x more than it was 5 years ago.
Allowing 0.5 sat/vB for example is just a basic adjustment.
Logical, although currently it's also like game theory. The miner that doesn't lower their min sats requirement will be giving the opportunity to include the sub 1 sat fee transactions to their competitors.
Plus it's probably also why we saw only one or two unmined blocks in Mempool.Space because those below 1 sat were not accounted for. But the fixed it now.
