This transaction is from someone else, in this scenario, do I have the option to bump the fee myself or it should be the sender?
I do not think, I'll spend more fee tho as this is only a 10$ worth of transaction.
edit: if I just let this be, it will just get confirmed eventually, right? Or will this be cancelled?
Ohh I thought the sending address belongs to you that means you are receiving which I saw three addresses with two having small amounts. Then you can’t possibly do a CPFP with that little amount. Yes you can wait and see since the fee rate is around 50 sats/vbyte now and your transaction is 20 sats/vbyte you should just wait and probably the transaction fee rate could get down more. Or better still if there is a way contact the sender to bump it using RBF.
Also the transaction could also get dropped back to the sender address at least after two weeks( although could be more due to nodes difference in purging transactions) if the transaction is not rebroadcasted again
