Do bitcoin accelerators really work ?

[krishnaverma]

I had one of my transaction stuck for quite long time. I tried some free bitcoin accelerators but it had no impact on the speed the transaction. Later the transaction got confirmed on its own. So I feel that these free BTC accelerators are just marketing gimmick to sell their paid options or to drive traffic on their sites. Do you agree with this ?

Viabtc accelerator works very well that is if your transaction fee is equal to what they use as their limit, and the transaction size also need to be below same level.

But for those who said they are offering free acceleration service most of them are lying and just using that means to get traffic from those who are in search to use free accelerator’s service, aside from viabtc accelerator almost all of them if not all offering free service don’t work.

[Mia Chloe]

Of course legit ones like ViaBtc works only for most of them you have to pay for an acceleration. Unfortunately the free hourly acceleration ViaBtc offers is actually being flooded by bots making it very difficult to use their free service.

[pooya87]

It depends on which one.
For example during 2017 spam attacks a lot of scammers started creating websites claiming to "accelerate" stuck transactions for money. Then they submitted these transactions in free accelerators or just took the money and ran.
The point here is that in these cases even if they work, they are scamming you nonetheless.

The only accelerator that can be legitimate is one run by a mining pool or a solo miner. Something like ViaBTC which is a mining pool and runs such a service. Others are most probably scams.

[Yamifoud]

Free Bitcoin accelerators don't work so well.
Nobody does to make your transaction be priority to confirm for free. Like if the current trx fee is 35 sats and you are sending just paying for 25 sats, that won't make it. These free accelerators don't give you an additional 10 sats to get the confirmation as I noticed when trying to use these services they only just add a few cents. It won't get the confirmation until the trx fees drop to where we set them.

Not a useless stuff but not recommended. Since it was a free service, we can't urge them to work on our request and help it out. That is why before sending, we also check https://mempool.space/ to have some views on how long our transaction to be confirmed especially when we set on the low priority size.

Viabtc accelerator works very well that is if your transaction fee is equal to what they use as their limit, and the transaction size also need to be below same level.

Viabtc hasn't worked well for a long time(since last I tried it). Since the inscription of ordinals on the Blockchain, these developers have flooded most free accelerators with bots. And when every you wait for the hourly free acceleration you find out that it has already been taken in less than a second. So no, viabtc hasn't been working well for some time now.

Op, you have to be really careful with some of these online accelerators as most of them are scam. You might end up paying for a service that might not work and at the end, your transaction remains unconfirmed. If you want to use some paid service, just use those of
https://www.antpool.com/txAccelerate
www.mempool.Space

There's also this free transaction acceleration service provided by a member of the forum and as far as I know, they've been working for long and still functional. So you might try they out if you have another stuck transaction
FREE/PAY BITCOIN TRANSACTION ACCELERATOR

[OcTradism]

It works and there are some Bitcoin transaction accelerators. The most favorite accelerator with free service is ViaBTC. For paid accelerators, service fees are widly different and you can get an overview on them with this thread.

Bitcoin acceleration services - Fee comparison

Because of abuse from Ordinal users, ViaBTC tightened their policy for free service but you can try them.
https://www.viabtc.com/tools/txaccelerator

FREE Submission

ViaBTC supports acceleration of 20 FREE transactions per hour. After ViaBTC generates blocks, the acceleration process is carried out in the order of user submissions. The volume of a single transaction must be ≤0.5 KB, and the transaction fee rate should be ≥ 0.0001 BTC/KB.

Sometimes confirmation on the mempool takes time before the confirmation complete, maybe as at the time you did your transaction there were many transactions ahead of you that needs to be attended to before yours.  Sometimes if you use low transaction lower than 20sats /vbyte, it might take longer than expected even with free accelerator tools. If you have used the medium transaction fee, it would have gone earlier because minners would place your transaction above others.

[mk4]

Back in the last bull market in 2017, I think I've tried almost every single transaction accelerator I've seen on Google lol and the only accelerator that actually helped is the one by ViaBTC. I'm not 100% sure, but the other accelerators just make it seem like they're "accelerating" your transaction but in reality they do nothing lmao.

[fuguebtc]

I have never used these tools, if I want a transaction to be confirmed quickly I will accept increased transaction fees, and for regular transactions I am willing to wait.

Are you using free tools and what are you expecting? If it were you, would you be willing to spend a lot of your money and effort to build a tool for everyone to use but not gain any profit? So don't complain about free things in this world, nothing is free or cheap that will bring high quality. Use a paid tool like Viabtc that everyone mentioned or increase the transaction fee for the next transaction.

[hugeblack]

A Google search will lead you to a bad result from services that claim to be free bitcoin accelerators, and all they do is rebroadcast that transaction. Therefore, unless the accelerator is linked to a mining pool, it is either a scam or it is rebroadcasting the transaction.

Examples of bitcoin accelerators:

ViaBTC            ------> https://www.viabtc.com/tools/txaccelerator
F2Pool            ------>  https://www.f2pool.com/user/tx-acc

As far as experience goes, Viabtc seems to work, (https://www.viabtc.com/tools/txaccelerator)

They have the free and paid services, haven't tried the paid though, but usually the free services is enough for everyone although there is a cap as to the number of transactions they can talk in an hour.

And as per their website, they have help accelerated 741909 transactions. And they are one of the first to offer this kind of services since 2018, so I think there is no gimmick from their end. Not sure about others though.

[Solosanz]

I agree with the other users, it depends on the site you use.

If you use the gimmick one i.e. rebroadcast site, your transactions won't be speed up.

But if you use the real one i.e. viabtc, your transactions will be confirmed ASAP.

Check the block #834006 there are 5 transactions added by viabtc (the blue color).

I used Viabtc about a week ago and there were still a few free slots open, even a couple of minutes after the full hour. Might have been just luck though.

For newcomers it's worth noting that even with legit accelerators it might take a few blocks until the miner gets lucky and the transaction finally included.

This.
As many other have stated, viabtc is the way to go.
I can also just tell good things about that site. In the past I was lucky enough to use their free service occasionally but the paid one also works like a charm.
Had btc stuck forever until I finally found that site and never had that problem ever since.  

[blckhawk]

ViaBtc is the only one that I know that's legitimate but you're as good as just waiting for your transaction to finish on its own because ViaBtc and probably any legitimate accelerators are being exploited by abusive crypto people that flood it with bots so their transactions are the one that's going to get the priority. It's not a gimmick as you might think it is but it's definitely a tool that's not properly created or utilized because not everyone can use it and finding other alternative accelerators would probably end with you arriving in a sketchy one and you end up getting scammed so just wait for it.

Demand going high and resulting in lesser available slots does not mean a service was not working well. Ordinals caused a lot of spam on the Bitcoin network moving users to ViaBTC in the hope of getting their transaction confirmed in a reasonable time, with a reasonable fee. Spammers and bots also attacked this service and made it harder to get those free slots.

This was however fixed after a while and the total free transactions were reduced to 20.

This is like saying Bitcoin did not work well cause ordinals were complicating transactions.

[ABCbits]

I would say no, unless it's either,
1. Offered by mining pool. While solo miner and miner (which join certain pool which let miner add arbitrary transaction) exist, i would say it's not reliable.
2. The service can provide proof they cooperate with certain mining pool.

And aside from wasting our time, i would speculate those fake/scam accelerator service might collect and store your data (such as IP address, TXID and browser fingerprint).

Viabtc accelerator works very well that is if your transaction fee is equal to what they use as their limit, and the transaction size also need to be below same level.

These days, ViaBTC require you to own account, pass CAPTCHA and more strict TX requirement which makes it usable again. But with minimum fee rate imposed by ViaBTC and current mempool condition, it become less attractive.

There are too many scams on the internet and if you are not very carful, you will get scammed. I have not used Bitcoin accelerator before because the need have not arise. My friends who have used Bitcoin transaction accelerator service before, said they did it from their wallet apps and I don't know the wallet they were using to store their Bitcoin but I believe that there are some Bitcoin wallet that offers free accelerator service, am not sure but only saying it based on what my friend said.

[Churchillvv]

You can not conclude that Bitcoin transactions accelerators don't work because you had a bad experience with one.

I one had a bad experience too with an acceleration vendor that takes fees from people claiming to accelerate transactions but they usually just put them in one of the accelerators and it's done then you pay them, after I discovered asked people with more experiences and I was directed to viabtc and surely it worked.

Now that you have asked question, I guess you wouldn't conclude that accelerators don't work because of your one experience.

[Crypt0Gore]

There are many fake Bitcoin accelerators out there, and it's been very long since I used one last, I don't always get stuck in Bitcoin transactions since I've started using mempool. space to check the actual transaction fee needed to send my Bitcoin to another address.

The last one I used and liked is viabtc, it's very genuine and it always works, though it is not always free, they have a limited number of free accelerators per day, or let's say every 24 hours.

Viabtc is now less attractive because of the new terms and conditions they have introduced but who am I to complain about it? I heard that many people are abusing the system so we get what we deserve even though I've only used like three times since 2018, when something is free, people don't know how to appreciate it, they will handle it as they fit.

[PrivacyG]

One thing I have not seen yet mentioned here is that for an accelerator to work, they need to mine a Block.  Unless they mine it and your Transaction is among the ones included by the Miner who got to mine the Block, it is impossible to accelerate your Transaction.

Accelerators work.  ViaBTC surely does.  I have no experience with paid accelerators since I rather not put myself on a priority list unless it truly is a big emergency.  I had Transactions stuck for DAYS before that have been successfully mined in under an hour after I accelerated it for free through ViaBTC.

[Blitzboy]

First, expectin priority transaction processing from a free service is optimistic. Despite claiming to have miners to speed up transactions, many services dont treat free users well. Why would somebody give away a premium service? Busines basics. You are right that these are often teasers to upsell you on a service you may not need.

We know Bitcoin's network is crowded. Miners prioritize high-fee transactions to generate money. That's gaming. Your transaction was likely stuck because miners werent motivated to pick it up soon. It was confirmed after network congestion resolved or your transaction became more profitable to mine.

The main takeaway? Understanding Bitcoin network dynamics is essential. Using external accelerators, especially free ones, is unwise. A risk.

Exactly it is not only about if they accept to accelerate your transaction but how fast can they do that and that’s where you see the ViaBTC accelerator been advised as most reliable because last time I check they have the 3rd largest hash power and at least in a 100 minutes they could get lucky to mine one of the blocks and that is explains why they also have limited number and time restrictions for the free services. The other ones I know of is the mempool.space and binance which you have to pay for them.

Also if it is paid service the Viabtc works just fine for that too, if you’re ok with the charges. It is even more faster than the free service ( it should be) because they do not only wait for the time they mine their own blocks before they get your transaction included in it, they just collaborate with other miners to get into theirs. So sometimes for faster acceleration it is better.

But for OP what’s best is migrate to a wallet today that allow the use of RBF feature.

Viabtc had a nearly constant share of the pie for the hashrate for years , they decided to limit the numbers of free tx because of $. nothing else
Average fee at 10$ and you offer 100 free spots getting just 2$ back, that's $800 lost an hour , $20k in a day, not the recipe for a profitable business, especially with earning so low on mining.

Viabtc hasn't worked well for a long time(since last I tried it).

Viabtc works perfectly!

There's also this free transaction acceleration service provided by a member of the forum and as far as I know, they've been working for long and still functional. So you might try they out if you have another stuck transaction
FREE/PAY BITCOIN TRANSACTION ACCELERATOR

He hasn't accelerated a single tx that wouldn't have been confirmed anyhow!
You can check the tx "added" yourself, they are always on the min fee for the block.

offer 100 free spots

Just for the record

By the order of submission, ViaBTC supports 20 FREE acceleration chances per hour.

AFAIK,they reduced the free spots from 100 to 20 on or before Jan 7 this year and now we need to login to viabtc account even to use the free acceleration and I assume these changes were made to stop the bots abusing the accelerator and also one account can only submit up to 1 free TX for certain time range which is not mentioned anywhere but also has been in effect already.
To @OP Viabtc is the only free TX accelerator remaining and it works fine which I tried couple of times even in the past week but the only downside is you need to be on time if you want to submit in the allocated 20 slots.

Yup that's why I said: "they decided to limit the numbers of free tx because of $"
When you see your earnings go below 6cents/th as a miner you start getting angry seeing how the pool wastes nearly 1BTC in rewards, not to mention than on top of that Viabtc was not sharing the paid fees with the miners, so it was a double loss for the ones mining with them. There was a topic about that back during the previous spam fest:
Transaction Accelerator Services, Is it fair for the miners?

The account requirement was to stop the bots indeed but the reduction was about money, why offer that much for free when you can can not only make more directly from adding tx and even more for forcing those who can't get a spot to use the paid accelerator? It's business and a profitable one, that's why every single pool has their own right now, and they even have backroom deals , like Mara which is mining a 3MB tx ever week or so.

Oh, just another thing
The mempool right now is so low a tx that will need to pass the 10sat/b (not vb) viabtc requirement would get confirmed anyhow, so no wonder it's 42 minutes and still 9 out 20 spots left!

[BITDV]

Not all tx accelerator is fake, such as viabtc they offer great service. But if you look at not reputable website from google most of them is fake, they just doing scrapping via PHP Curl or post API. Ridiculously they ask a payment first before post a data to real tx accelerator

Yes, now I understood their business model. They are giving free option which when used by a user will never work and this is when they promote paid service to him.

Most of them are just carp/fake accelerators that just baits users to their site to increase their traffic. There are some paid accelerators that are legit, and they do give some free "acceleration" access hourly, but you need to be extremely like to be one of those first 50 person to use their acceleratior service. For the paid services you would be actually paying more than what you would have paid if you added extra fees when making the transaction. The best thing to do is to check the current mempool and determine the fees. Based on that fee, make the transaction. You will be paying a lot, but lesser than what you will be paying when using those accelerator services.

[Adbitco]

Accelerator is working just that it depends on the one you tried using, I think last week I tried making transfer with a very low gas fee after I waited for about 5 hours the transaction didn't confirm so I have to signed up for a viabtc accelerator and input my txt id after 30 minutes or so my pending transaction was confirmed.

So it depends on the kind of BTC accelerator you used otherwise there are some that doesn't confirm very fast even when network congestion were disturbing that is the accelerator I was using, although then I hardly meet the free acceleration space.

When your transaction is in stuck, your best bet is to use a legitimate transaction accelerator that includes your transaction in a mined block or contact a person who has access to mining pools and can include it. Your another option is to not use fake transaction accelerators (they only broadcast transactions), just do nothing and hope that nodes will forget your transaction and you'll be able to resend them again.
Most of the time you should be able to use Replace by fee or Child Pays For Parent option.

Hugeblack gave you a good list of real transaction accelerators, I'll quote his post.

When it comes to bitcoin transactions then the correct term is fee rate not gas fee. Gas fee is used in other altcoins such as ethereum.
Viabtc is a legit accelerator, indeed, but your transaction needs to meet some minimum requirements to be accepted such as paying more than 0.0001BTC/KB and its weight must be less than 0.5kb. Besides, the free service accepts only 20 transactions per hour so you need to be very quick.
