It depends on the wallet that you are using and whether you are the sender or receiver. What wallet software are you using?

You keep on waiting for some more time, after a certain time it will be deleted! In the past I was the same, in general you should avoid to do so

Some wallets support Fee Bumping, see https://en.bitcoin.it/wiki/Fee_bumping

By using a harder fee, in blockchain.info, you can make double spent, I think. But how is your transaction stuck for 7 days? Use way higher fees then.

You can check this video that helped me as well to double spend my transaction. It works with blockchain.info only though and if you are using this wallet, you can just wait till the transaction is dropped from blockchain.info only (you should get a message: Transaction rejected by node) and then your bitcoins would be back in your wallet. Just spend them again with a higher fee. It would be marked as double spend then.


If you aren't using blockchain.info, use viabtc.com/tools/txaccelerator/ is the fee of your transatcion is above 10 sats/byte or contact Quickseller and pay him the miner fee to confirm your transaction.
