let's say confirm very small fee transaction within 2-24 hours
how much it costs for them ?
and where can i find service/ people who can do this service ?

You won't need any transaction accelerator if you included a sufficient miner fee. You can use the following guides to get the closest to accurate miner fee for your transaction:

• https://bitcoinfees.earn.com
• https://btc.com/stats/unconfirmed-tx?
• https://estimatefee.com

If a situation where your transaction got stucked arises, then transaction accelerators can help you with that.  
A good example would be https://pool.viabtc.com/tools/txaccelerator. They are offering both free (with prerequisites) and paid accelerations

I know these sites already all i want is knowledge
How much it costs to miner to acclerate single transaction ? within how much time ?
Which tools he need in order to do it ? how much costs these tools ?

Thanks for the help.

So you're asking if a miner can specifically pick a transaction to confirm? He can but he needs tons of ASICS (Mining hardware specifically for bitcoin) to produce a significant amount of hashpower so it'll definitely be expensive as you will need a mining farm.

how services like confirmtx.com running ?
i dont believe he has minning farm, he's a kid from hacksforum.

If block is empty - it does not cost anything for miner to accelerate transaction. They manualy include transaction into block-to-mine.
If block is full - they need to remove similar-sized transaction A and replace it with accelerated transaction B. If miner fee of tx B is 1 satoshi and miner fee of tx A is 10 satoshi then cost of accelerating tx B is 10 - 1 = 9 satoshi.

Now viabtc accelerator are not no more good for the free transaction acceleration. I see only every 100 people who trying to accelerate only able to do that. Antpool is the fine one to accelerate your transaction with the free of cost. Just signed up there and can be able to accelerate it.
After free accelerator tool still there are some paid services in the market and they will ask you to pay the charge according the value of the amount you are transferring out.

Confirmtx turned scam sometime ago, but some people still are using them. They claimed to be working with a large group of miners to push transactions through big mining pools, but nothing to back it up, no transparency. There has been couple of scam accusations against another accelerator said to be cooperating with main Bitcoin pools, BTCSpeedy. Better to use appropriate fee, rather than losing money on these shady accelerators.

Coinfirmtx was dope in the past.
They acclerated my transactions even for free...  lately,  it lost his potency .
but how they did it before ?

Are you kidding us? The services board is full of suggestions of free bitcoin transaction accelerators! The first transaction is actually for free and if you want more you will need to use services of another guy or to pay the first one. The prices are different here, the one who's help I have used asked for 0.0001BTC which is actually not so much, but then I have added to that the transaction fee and I decided that it doesn't worth such costs, I better wait a bit more for the confirmation.

This is why I don't really bother at all on using those accelerators specially on those paid ones.There might still some legit but I do still doubt since there would be no transparency which do really hesitates me. Even using that free viabtc tool do really pissed me since everytime I do enter even on the 1st second for the hour/reset time. It do showed up beyond limit that's why I don't bother on these stuffs.I would willing to pay fees depending on how do fast I like to be confirmed.

Free doesn't exist in this world. If someone is offering transaction accelerations for free, he hopes to get tips or perhaps positive trust, even when that person isn't explicitly stating it. It's well known that someone who is desperate to get something done (in this case getting a transaction confirmed), will feel the need to give something back, and in case there are no funds, the easiest thing to do is to leave trust since it's free. With some logical thinking, there is basically no need to use these accelerators, where you can also just accept the fact that you have to wait a few hours.

That's a matter of "opportunity cost." There is limited block space. Including low-fee transactions in blocks means missing out on higher-fee transactions. Rational miners want as much fees as possible. So a legit transaction accelerator service is trying to do one of two things. They might want even more fees than they could get from mining (see BTC.com's accelerator). Or they want to achieve some larger game theoretical goal by claiming goodwill (see VIAbtc's accelerator).


Most of the "services" listed on the forum won't get you anywhere. They generally don't really work with miners. VIAbtc, BTC.com and Antpool (if their accelerator is still active) are your best bets.

we have many of them doing it for free at the services section in this forum. You can use this person and very effective, https://bitcointalk.org/index.php?topic=2597277.0.  I don't think he do collect any fees for his service and most times some of them only give you micro task for the acceleration. I have never come across any pay services for this online though I had that there are many of them!

If they just have to include the unconfirmed transaction in the next empty block that shouldn't cost them anything. I think.
Still this forum is flooded with transaction acceleration offers, new ones appear each day because many realised that could be a great source of income for them. But better to prevent than cure, so always use appropriate fee. Sometimes even with adequate fee transaction might need longer transaction time for confirmation but still you will not need acceleration service.
