This might be a weird question, but I have a transaction stuck in the blockchain for 5 days now that the sender sent with too low a fee associated. It doesn't have RBF enabled, so I'm wondering if it is possible for me to personally contact a miner and pay them an extra fee in order to help confirm this transaction? Thanks for any help.
So I pointed out the obvious that now all transactions 'can' be RBF'd.
So while it may or may not be possible for him to have the transaction RBF'd by the sender,
he has stated the term RBF in the opening post ...
If he has no control over it and was intelligent enough to say "RBF" in the opening post, then doing a Child Pays for Parent is the other option.
Assuming he's ignorant of what RBF/etc are seems a silly thing to do when he's used the term in his opening post.
