Hello,

Since you're using bitcoin core you can do a full rbf on it where you can cancel an unconfirmed transaction and send it again with a recommended fee

Bitcoin Core

Bitcoin Core makes making Full RBF transactions very easy. Simply go to the transactions list, right click the transaction that is stuck, and choose the "Abandon Transaction" option.

If that option is greyed out, then you must restart Bitcoin Core with the -walletbroadcast=0 option and then you should be able to use "Abandon Transaction".

If the above two options fail for some reason, then you can start Bitcoin Core with the -zapwallettxes option to clear all unconfirmed transactions from your wallet.

Once the transaction is either Abandoned or cleared from the wallet, you can simply go to the Send tab and send the Bitcoin again but make sure that you include a sufficient transaction fee.

Or you can here the whole thread here: https://bitcointalk.org/index.php?topic=1802212.0
A good guide to know the recommended fee of a transaction: https://bitcoinfees.21.co/

Do you have to re-send the transaction again to create a double transaction, or can you simply keep the recovered spent coins?
