Before increasing the fee you may want to see the priority of that transaction in the mempool. Use for this https://blockchair.com/bitcoin/transaction/xxxxxx where xxxxx is transaction ID (txid). If the fee is reasonable you still may try to accelerate transaction by using either Antpool's or ViaBTC's accelerator.

The mentioned sites are filled with bots. He doesn't have a chance to submit his transaction, not with the current mempool state anyway.

I know this but it would cost him nothing to try. Jugging to my happenings the mentioned accelerators sometimes help. Still there are paid accelerators but user have to decide himself what is more cost effective to use them or RBF.

I tried accelerating one of the transactions with ViaBTC and it did nothing. Never tried Antpool, though. Is that a free accelerator?

ViaBTC still works as far as I know, but is heavily oversubscribed and difficult to get accepted... like you need to submit within the first second of a new hour, and even then it's not guaranteed you'll beat the bots Tongue

Also, their broken system still calculates your fee using sats/byte... not sats/vbyte... So, if you've used a SegWit transaction, it's possible that your 10 sats/vbyte fee won't meet their 10 sats/byte minimum fee requirement. I've actually tested this with a transaction that I was sending a few months ago... I had sent with a 10 sats/vbyte fee, but their system said that my fee was too low (recorded it as ~6 sats/byte).

As for Antpool, as far as I'm aware, that one has not worked for years. From memory, someone published the details here and on reddit etc (it wasn't well publicised at the time and was a "hidden" service) and then it would appear that it got flooded to the point that Antpool just quietly stopped using it... the page is still accessible (if you know the URL), and it'll still say "transaction accelerated" etc when you submit a transaction... but the transaction will never get mined (by AntPool) prior to it being at the "correct" fee level Tongue

All you are doing by increasing the fee, is increasing the odds that your transaction will be included in a block in the near future... but it will likely never be 100% guaranteed.
There are currently nearly 100,000 unconfirmed transactions... about 70-75 blocks worth... this new bull run has flooded the network with transactions Undecided

During the week I would have said the same but the weekend is around the corner, with no insane price swings even if we have some kind of volatility I doubt we won't see the mempool cut in half by Monday morning. The peak was around 95M around the same hour yesterday, or should I say better 24 hours ago with those timezones, now we're down to 72, if the damn hash rate recovers also so we could mine blocks at the usual pace we will see nearly empty mempool next week. Or at least one that allows 10sat/b.

Bitmain's accelerator, I don't know if it still works, till now Viabtc has always helped me.

OP, unless you really need to get that bitcoin sent I would probably just be patient.

And avoid payment services that require one confirmation in 8 or 12 hours or they will cancel your order and then return your coins (minus another fee) when you finally get a confirmation. FY Coinpayments! Undecided

Ugh, I was in the same position as OP recently with the network being so congested and fees running so high. I tried accelerating one of the transactions with ViaBTC and it did nothing. Never tried Antpool, though. Is that a free accelerator?

OP, unless you really need to get that bitcoin sent I would probably just be patient. If you keep increasing the network fee, it's just going to cost you more money--and with bitcoin at $22k, those fees can add up very quickly. I get that waiting 24 hours might seem like forever, but it'll go through eventually as long as what you set the fee at was reasonable.

That's kind of what I figured, since everyone who's trying to send bitcoin is in the same boat.

There is no real guarantee with how long it is going to take, even "after doing all the increased transaction fees"... there are simply too many variables Undecided

For instance, if the "best" fee is currently 100 sats/vbyte... and even if you send with 120... you could still end up waiting for a long time if no blocks are mined for an hour... and 10000 more transactions are added that all send with fees higher than 120 etc.

All you are doing by increasing the fee, is increasing the odds that your transaction will be included in a block in the near future... but it will likely never be 100% guaranteed.

Thanks, I would do just that, but is this sure that the transaction would go through fast after doing all the increased transaction fees, from the look of things the traffic is elephant-like heavy and my mempool depths is cripping in it movement, is this just to say this a slow times for transaction to be made, and for doing transaction ATM its best tsk do it by the weekend, probably then traffic will not be as congested.

If bumping the fee is not an option (e.g. because RBF is disabled), you still the possibility to use CPFP.

If you control one output (e.g. the change output), you can create a transaction spending this unconfirmed output.
Choose the fee high enough to pay for both transactions and a miner will include both of the transactions into the block.

although I clicked on the unconfirmed transaction itself but can't see "Bump fee", maybe their are difference between mobile phones and computer systems.

As Rath_ said, look at the bottom left corner, like here:

If you don't have it then it means you haven't clicked yes on the pop-up asking you "Should this transaction be replaceable".

I've managed to get a spot on ViaBtc in the morning for a friend, using the desktop, so it is not really impossible, besides ViaBtc has been quite lucky the last 24 hours, mining a bit more blocks than usual. Also funny, they've mined a block just 2 minutes before I managed to get my transactions in their queue. Angry

I have just tried working with it, and I have ransacked my electrum but can't see, "history" tab, may be I should make it clear/mark it out that am using the electrum on my phone and not a personal computer, although I clicked on the unconfirmed transaction itself but can't see "Bump fee", maybe their are difference between mobile phones and computer systems.

Can you check if you have "Replace-by-fee" enabled in the Electrum settings? If so, you should see a "Bump fee" button in the transaction details in the bottom-left corner.

You only need to right-click on the transaction in the "History" tab and select "Bump fee".

I would just add that the new fee should be set in accordance with the current status of mempool and with how fast/slow we want to get the first confirmation. Currently, for the next block you have to pay about 170 sat/bytes.

So am asking so I don't fall into the wrong hands -scams- is there a way to increase an already sent transactions, and the wallet was electrum, pls I would appreciate it.

Yes, it is fairly easy. If you are running the latest version of Electrum then every of your transactions should be marked as replaceable by default. You only need to right-click on the transaction in the "History" tab and select "Bump fee".

I am not at all nimble fingers with technicality to, but I am nimble at trying to learn. I recently made a transaction its been more than twenty four hours already and the transaction hasn't been confirmed I know low transaction fee is one reason for slow/delayed transaction. So am asking so I don't fall into the wrong hands -scams- is there a way to increase an already sent transactions, and the wallet was electrum, pls I would appreciate it.
