There isn't correlation between more miners/pool with decreasing transaction fees. Only SegWit, LN or/and increasing block size which can decrease transaction size.
If there where miners/pools concentrating on microtransactions (with lower fees) this would help getting them faster approved!
The current problem is of course, that miners are trying to make as much profit as possible. Maybe a pool choosing transactions at random for their blocks would make sense :0
If there were pools like this, the overall transaction fees would sink.
Please correct me if I am wrong.
I think there are people out there, that run "hobby miners" for the sake of supporting the "system".
Certainly not enough of them to make a very big difference though. I think if some "miners" educated
themselves a little further, about where to use their hashing power, these things could improve. Alot
of "miners" just hook up their machines, and aim it at the biggest pools, thinking that "bigger is better".
Have a visit in the mining pools board, and you'll soon notice, there's alot of "miners" who want to do
something about this issue.
Another thing I think is "bogging down" BTC, is the massive amount of "get rich quick" people. They have
just jumped onto the blockchain, making small $50 investments, and putting $10 in 5 different online wallets.
Then they decide, they don't like something about one of them, so they move $10 to a wallet they like. That
wallet now has $16, cause they had to pay the transaction fee. They decided to move ALL of their money to
a wallet, that has the always promised "lowest fee". These little meaningless transactions are slowing the
system down.
A little bit of education about BTC, and how EVERYTHING works, could really benefit ALL of us. And at the
end of the day, that's what this forum is supposed to be about. Unfortunately, you can lead a horse to water,
but you can't make it drink. Unless you promise the horse it can make a living off signature campaigns!
