No problem. Happy to help! As expected, the mempool started to empty out a few hours after my last post, and it looks like both your month old transaction and your new one were both confirmed together in block 674,790.

For future reference, most good wallets, including Bitcoin Core and Ledger Live (to an extent), have a feature known as "Coin Control". This allows you to select exactly which coins to spend in any transaction you are creating. You can choose not to include coins which are unconfirmed so you don't run in to a similar problem like this in the future, where an unconfirmed input is delaying the rest of the transaction. Or, conversely, you can choose to include unconfirmed coins for the very reason that your new transaction will help to speed up the confirmation of the old unconfirmed one. This is known as a "child pays for parent" (CPFP) transaction.

Option one is to keep rebroadcasting both transactions and be patient. Once the mempool starts processing transactions at 68 sats/vbyte, then they will both go through. There is quite often a drop in the mempool around the hours of 0100-0400 UTC (so in around 5-8 hours time) as there are relatively fewer transactions being broadcast around this time, so there is a chance it could confirm then. 68 sats/vbyte is still a good fee, so I wouldn't expect it to take more than a couple of days to confirm at most. This is the simplest option.

Option two is to abandon the transactions, wait for them both to drop from the mempool, and then make a new transaction from scratch spending your coins. You will likely be waiting several weeks for your higher fee transaction to drop from the mempool, however.

Option three is to make an RBF transaction to replace your latest transaction (which is RBF enabled), while removing the unconfirmed input (which is not RBF enabled). This will allow you to move the majority of your coins immediately (provided you pay a high enough fee), and leave behind the low fee unconfirmed coins which you can move at a later date when the transaction finally confirms or is dropped.

This transaction was made a month ago: https://mempool.space/tx/a9b32b0d73abb9a84b30d5e38aa8877cd547d2131d71ab5aa50fe9a14c8b7fef

You sent 0.00002633 BTC to the address 1Gue6uuswhbZSQtBSsSuYao2DouEqpHLBd, and received 0.00332251 BTC back as change to the address bc1q9lqmchja8qv7rq2x6kwh9jh9qy9u6ksm9aa583. That transaction is still unconfirmed, but you have attempted to spend the 0.00332251 BTC from the address bc1q9lqmchja8qv7rq2x6kwh9jh9qy9u6ksm9aa583 in the transaction you broadcast today.

As I explained above. Your current transaction is attempting to spend an input which most nodes do not know exists since the month old unconfirmed transaction has been dropped from their mempools.

Because there is nothing wrong with the address. The address works just fine. The problem is with the transaction you have broadcast.

Again, your money is not gone. If the transaction does not go through, then the bitcoin will never leave your Bitcoin Core wallet and you can simply attempt to spend them in a new transaction.

This will not make a difference. The network has no idea if you confirmed the address on the Ledger or not. It will send to any valid bitcoin address.

I think the issue here is that one of your inputs is unconfirmed. I found your second transaction here: https://mempool.space/tx/d7b28ea40264270ef571d5952784972151573e6dba8fdb5230b8415ca4b018e8

It pays a good fee of 89 sats/vbyte. However, the input from address bc1q9lqmchja8qv7rq2x6kwh9jh9qy9u6ksm9aa583 is unconfirmed, and only pays a fee of 1 sat/vbyte. Combining those two transactions together gives a total size of 692 vbyte and a total fee of 46,998 sats, which works out at 68 sats/vbyte. This is still high enough for the your transaction to be confirmed fairly soon, but the problem being that most nodes have dropped this unconfirmed transaction since it pays such a low fee and is over a month old. Because of this, they will not broadcast or relay your second transaction because as far as they can tell, it is invalid.

I've used blockchair to rebroadcast both the low fee unconfirmed parent and your new transaction. It may or may not work.

If the address is correct, then your bitcoin is not lost, so nothing to worry about. It will either reach your Ledger address, or it will not leave the wallet you were sending it from. It will never end up lost "to the ether", as you put it.

How did you attempt to increase the fee? What wallet are you sending the coins from? Bitcoin Core? Are you sure you have broadcast the transactions and not just saved them locally?

Are you willing to share the Transaction IDs of your various transactions so we can take a look?

It depends.

The addresses generated by Ledger Live will be correct and accurate provided there is no malware on your computer. Confirming the address on the Ledger hardware wallet is simply an extra step to be doubly sure that the address is correct. Look up the transaction on a block explorer and check the address you have sent coins to against your wallet now. If the address is part of your wallet, then you have nothing to worry about, and it is simply that the fee is low and the transaction remains unconfirmed.

If the address is correct and you need the funds to confirm sooner, then you can either increase the fee a second time using RBF, or use a CPFP to confirm the transaction.

What you mean?, what is said address?, if you didn't sign or confirm it on ledger the transaction won't happen.

Maybe yes if you sent to phishing address and maybe no If sent to an invalid address your transaction won't be processed by the network.
