I'm slightly stuck. I hadn't bought any BTC since Oct 2023 and so didn't notice that the network fees had got so high so now I have some BTC on an exchange and I'll have to pay £20 or so to send it to one of my wallets so I've been keeping it there hoping the fees will come down.
But that got me thinking. How can I determine a decent custom network fee amount using the BTC Core wallet? Also I'm assuming that if the custom fee is too low it'll eventually just return to the source because no one will confirm it. Is that true?
I'd like to know how to determine what a reasonable network fee is.
