I do own the UTXO's. I received the first transaction to my blockchain wallet. The second transaction was from my blockchain wallet to my Coinbase address. The second is shown as pending in my Coinbase, so I cannot send it again with a higher fee without adding money to my account.
your address is 189komZ8b...? and your 1st tx has 2 unconfirmed inputs (from 2 different txs)
those 2 need to get confirmed first, and to CPFP this tx (by your 2nd tx) would be somewhat expensive
are these two utxo belongs to you?
1Kh9G2EBL... (U) (0.00989736 BTC - Output)
1FUPtCrmG... (U) (0.00989586 BTC - Output)
Does it make sense to add money to my account and then try to send the same amount of bitcoin to another address I own (within coinbase) that is the same amount as the pending transaction with a high fee?
I tried making a new transaction to do this vis coinb.in but it gave me an error when I tried to publish (after signing with my key). Wondering now if I can just fund my coinbase and resend to another address with higher fee to accomplish the same thing.
Your coinbase "deposit" address? your coinbase account?
No it won't work that way. It won't affect your pending deposit transaction (tx2: 553b768b3a...)
