Can increasing a tx gas fee slow down a transcation because it'll be put into the end of a queu in a pool?

Question

I send a transction, then, every 1-2 hours, I keep increasing the gas fee. I've done it a few times. I've noticied that after several hours that my gas fees isn't still high enough. However, at some point the estimate time has descreased while the current gas fees have increased. Does this mean that the longer a transcaction remains in a pool, the closer it gets to the point of being processed? Or is it simmply the gas fees that matter?

In there's indeed a queue, because increasing gas fees creates a new Tx, does this mean that simply creasing them will put my Tx at the end of the queue in a pool and therefore may not help much? And if I had stuck with my 1st Tx with the lowest gas fees, it'd have been proceesed with that low gas fees, faster that the new "speed up" Tx?

Answer 1

There is no real queue. Mostly it's just about the gas price.

I say "mostly" because in theory the miners can include whatever transactions they wish in their blocks. But in reality they mostly include them in the order of gas price - that way they maximize their income (they get to keep the gas fees).

So it shouldn't make much difference whether you keep "refreshing" your transactions. The only thing that might change is that it may take a while to get propagated to most of the network, but this time shouldn't be anything more than maybe a minute or so anyway.

So any fluctuations you see are based on fluctuations in gas prices.
