I know that it is possible to do CPFP again (up to 24 times as far as I know then the 25 will be rejected), but, since I am the sender now, my question is if it is possible to replace by fee the stuck CPFP transaction? Is it possible?
AFAIK, that "
24 times" is
not the number of "
retries" but the number of unconfirmed UTXO chain from the unconfirmed parent transaction. [

Regarding your query, you can use RBF as long as it's flagged as "
RBF" by enabling the right settings just as TryNinja said.
