You can.
The method mentioned by DireWolfM14 is called child pay for parent (CPFP) and can be implemented by the receiver.
To do CPFP, the only thing you need to do is spend the unconfirmed output with a high fee.
Thank you for your answer, hosseinimr93. But can I spend that amount of 0.00109 BTC
although it doesn't appear in my wallet? I can only see the transaction on a block explorer, not also in my wallet. I know that some wallets show unconfirmed transaction, but mine (Bitcoin Wallet for Android) doesn't.
Blockchain.com shows the time it last "received" a transaction... currently, your transaction is showing with a datetime received (in UTC) of:
Received Time: 2021-02-11 17:05
[...]
I suspect that blockchain.com rebroadcasts transactions
As I wrote above, the transaction doesn't appear at all in my wallet... And, if Blockchain.com keeps rebroadcasting it, doesn;t that mean that the transaction will never be forgotten? And, as a consequence, the funds will never be returned to sender's wallet...?
it seems that transactions below 4 sats/byte (!!?!
) are being "purged"
If those transactions would be purged, I think this would be a good thing for me, I guess, as the funds should reappear in the sender's wallet, thus he could resend the amount with a bigger fee.
