How exactly does a Bitcoin/crypto transaction get linked to IP address/device/location?
I still don't understand how one's IP address can be identified from a Bitcoin transaction. Can anyone explain this? I understand how Blockchain analysis can be used to link transaction to a particular wallet, etc., but I'm still really confused as to how transactions are linked to location or device.

Bitcoin transaction fees in wallet app and ledger device confirmation do not match
Setting up a ledger nano s, sent .0001 btc (+fees, .00000185 btc) from coinbase to it (segwit address) as a test. tried sending .000055 btc back to coinbase and the preview said it would use .00000166 btc for fees, so I confirmed the address and pressed the confirm button on the ledger. it used .000045 btc for fees instead of the previously quoted amount, using up the whole amount I had in the wallet instead of the ~half I wanted to for testing. now I sent another .0001 btc to my ledger and once confirmed tried sending half back and getting the same issue, even if I set the fees to custom at 1 sat/B, the quote says .00000166 btc fee the transaction, but then when the ledger device itself asks for confirmation it quotes .00045 btc once more, so I reject it. Anyone know what's up with that? Edit: So I think I've figured it out, since the minimum transaction amount is .0000543, there wasn't enough funds in my wallet to send the rest of the funds to the change address, so it just lumped the rest of the funds into the fees.
