At the moment, no. You currently need a fee of around 120 sats/vbyte to get in to the next block.

Assuming your CPFP transaction is around 300 vbytes in size, then combining that with your current transaction of 369 vbytes which pas 932 sats, then your new transaction would need to pay a total fee of ~80,000 sats. You can pay all 35,000 sats as a fee, but that would only bring you to an equivalent rate of around 52 sats/vbyte, which at the moment is still around 7 MB from the tip. That's still a lot higher than your currently unconfirmed transaction though, and might confirm within the next 12-24.

Well, using a proper wallet with RBF enabled, you'd be able to increase the fee afterwards by replacing the transaction with a new one paying a higher fee.
Unfortunately your mobile wallet doesn't allow to do that.

While switching to a better wallet won't help you now, it might save your some headache in the future.

I don't follow where you have lost 18€ in fees. Did you withdraw money from Binance to your Android wallet for the sole purpose of performing a CPFP? And Binance's withdrawal fee is 0.0005 BTC? That's ridiculous.

However, if you want to do it, then make sure to use a different wallet where you can exactly choose the UTXO and the appropriate fee yourself (e.g. electrum) by exporting/importing the private key or mnemonic code.

The priority will not be enough, it will probably just check the total of the highest paying 1MB worth of transactions and adds a few sats on top, which won't be enough in your case, of course, it will speed up the stuck transaction by a lot, but don't expect to get 1-5 block confirmation. I have not used this wallet but they mention "Full control over fees" on their website, which means if you dig a little you would find "custom" fees or something like that.

I see over a 100MB of the transaction with fees above 3 sats/byte, chances are his transaction will eventually drop in two weeks or so.

OP, your only two options are CPFP and paid transaction accelerators such as Viabtc and Poolin, you need to run the math for both and see if any of those options makes economical sense to you, if not which is more likely - patience is king.



The current priority fee is 100 sat/byte, you paid 2.5 sat per byte for a 369-byte transaction so that's a total of 0.00000932 BTC, so you are short of 0.000369 BTC, paying 100 sat/byte for the child transaction won't guarantee your transaction to go through, you need to add that extra missing 0.000369 BTC so that the average fee of both transactions is 100 sats/byte.

It seems like the bc1 address is indeed you change address then, but your wallet has automatically sent the change from your legacy outputs to a segwit address. I wasn't aware that Bitcoin Wallet for Android did this.

You can use this 747 satoshi to perform a CPFP transaction, but the problem you have now is that it is not enough to perform a CPFP transaction by itself. You would need to deposit additional funds to your wallet, and then spend those additional funds along with the 747 satoshi in a further transaction. While possible, this becomes significantly more costly since you have to make two further transactions and your second transaction needs to include two inputs.

Conversely, given how full the mempool is with low fee transactions, and it showing no sign of clearing down to 2.5 sats/vbyte anytime soon, you could be waiting for a week or more for your transaction to confirm, or it might never confirm at all and be dropped from the mempool. If this were to happen, then you can simply try to make the same transaction again but ensure you pay a higher fee this time.
