BTC tx accelerator works really?

[RapTarX]

I have seen a few services in the forum who have offered btc tx acceleration service for free. Do they really work? Have you ever used any such of service out of viabtc one? If you have, please share your opinion or experience on such services. I have never used them though.

[The Sceptical Chymist]

I have yet to find one that works via Google search, and I've tried quite a few.  During previous network slowdowns, there used to be some threads created by members saying they could accelerate transactions, but I think most of them turned out to be scams. 

And man, I wish I did know of a good one at times like these, where the network is congested as hell and the fees are outrageous.  If anyone knows of any legitimate ones, I'd love to hear about them.

[bL4nkcode]

I knew most of these free offers on services board just use free accelerators as well as those who charge for fees, well, there are still some like QS. As what I read QS have access on some mining pool, I wonder if he still into it and taking offers to accelerate pending transactions.

Btw I used antpool and viabtc before, I wonder if antpool's accelerator still working though, didnt use it for a long time now.

[Bttzed03]

I can no longer count how many times I tried in viabtc but zero success so far. It's so tough to get in. I always get "limit exceeded" or some error. I don't know if my timing was off or others are just too quick that one second is already too late.

I can't say for sure but it seems most of these free services are only rebroadcasting your transaction. If you're your fee is low, it will only be ignored by miners again.

I am not sure these bitcoin accelerators really work but i usually go to bitaccelerate and put the hash and see them push the transaction but that is when there is not much congestion but after this week it is not working after inputting two times then they are showing that the transaction is not in their database. Usually bitaccelerate works, may be any fees above 50 SAT/B might work.

viabtc usually never works when the network is congested .

That's not an "accelerator". Like you said, they push (or better, [re]broadcast) the transaction. If your transaction is already on the mempool, it does nothing. The only reason someone would need to rebroadcast a transaction is if nodes start to drop the unconfirmed transaction from their mempool. But then you are back at the start again.

The only kind of accelerator that does work are the ones offered by AntPool, BTC.com and ViaBTC. They can, if they want, put your transaction on their mined blocks. All the other websites are either doing that for you or just scamming you.

TLDR: If someone comes here claiming they will accelerate your transaction, they are scammers trying to fish for donations or merits. Unless they have direct connections to mining pools (unlikely in most cases). Period.

I wonder if antpool's accelerator still working though, didnt use it for a long time now.

IIRC, I just tried to use it a few months ago but it doesn't seem to work anymore. Viabtc is still the best accelerator for me that's free to use. I always get to accelerate with viabtc and that's why I'm paying the fee a bit higher than what they are requiring for them to accelerate one transaction.

viabtc usually never works when the network is congested .

It works for me even if the network is congested. It's actually a life saver if there's a lot of unconfirmed transaction, you only need to be quick when you accelerate because there are other users who are also waiting to be accelerated through viabtc and you need to be faster than them.

[khaled0111]

Technically, the only one who can accelerate your transaction is a miner or a mining pool by including it into the block they are working on.
So, as TryNinja said, anyone who offer such service and is not a miner/mining pool, is likely going to scam you (in any case: do not disclose more than the tx id).

I can no longer count how many times I tried in viabtc but zero success so far. It's so tough to get in. I always get "limit exceeded" or some error. I don't know if my timing was off or others are just too quick that one second is already too late.

That's because they only accept 100 transactions/hour, so you have to be very quick. Besides, your transaction fee rate must be above 0.0001btc/Kb.

This one definitely works: https://www.antpool.com/user/prioritiseTransaction.htm?m=savePrioritiseTx
I always send the BTC transactions with a mining fee of over 14 satoshis per byte, viabtc accelerator will solve the confirmation asap if the minimum fee is over 10 satoshi per byte. The accelerator above also has been an alternative for me and I come to ask from forum members if the transaction stuck for 24 hours.

During congested times there are hundreds of trying to do the same thing as you refreshing the page at exactly xx:00:00, I helped in the past a few guys getting their tx confirmed on ViaBtc and managing to squeeze in but yesterday when I tried I ended up with an unresponsive page and a timeout error hit refresh and saw the Cloudflare offline error so I gave up, and this while using a desktop, probably on mobile it will be a pain in the ass.

Wow, you've managed to arrive at exactly the wrong conclusion.
You were tricked into believing that bitaccelerate was indeed helping you getting the transactions confirmed because you were sending them when the network was not full and they would have been confirmed without you doing anything extra. The proof is that when the mempool is full it doesn't do a thing for you.
It's as useful as Lisa's anti-tiger rock!
On the other side, viabtc is the only one that can help you in these cases (for free) because they can actually confirm the transactions they chose in the blocks their mine with their pool.

Short answer is No. I would rather pay some fees to the miners and wait for the transaction to confirm than beg on someone's thread to make it seem as if the thread topic is legit.

Its a nicely planned gimmick/confidence trick run by some users on this forum. People tend to cheap out on fees and then come to ask their help, the helper does nothing but replies after a couple of hours saying that its been accelerated.

Now imagine going to this guy everyday, you will definitely feel one day that you should tip this person for their "hard work" - thats all how the scam works.

Have you ever used any such of service out of viabtc one?

ViaBTC's accelerator used to work at one time. Its defunct now.

If you have, please share your opinion or experience on such services. I have never used them though.

Would suggest you to pay fees as per the internet sites which keep track of current fees instead of using these services.

PS: I am yet to see any scientific proof that these services really work.

[SFR10]

As what I read QS have access on some mining pool,

IIRC, "kano ^[active]" and "macbook-air ^[inactive]" have also an access.

I wonder if antpool's accelerator still working though, didnt use it for a long time now.

AFAIK, this link has been dead for a very long time ^{[it gives an error on my side, I've tried changing my IP but had no luck]}.
- Can someone confirm if they can view this page normally ^{[for those with accounts on antpool]}?

ViaBTC's accelerator used to work at one time. Its defunct now.

I still use it on a regular basis ^{[it's a bit harder but still functioning]}...
^{Fun fact: Our last campaign payment [round 31] got its first confirmation through the use of ViaBTC's free accelerator.}
Update:

Yes. I even grabbed a random transaction which is in the mempool and submitted it through them. It says the transaction was accelerated, so apparently, it still works (and probably even better than ViaBTC which never has free slots).

That's strange, I can't access it

Update 2:

The last time we tried to ask CoolWave about it, SFR10 remembers it I am sure, it ended up being a childish thread in Reputation.

I do remember and I agree, it was a bit childish

ViaBTC works quite normally all these years and does not work for those who have not read the minimum requirements, and do not know how to add a transaction. A few days ago, I helped a member get confirmation for his transaction, which was unconfirmed for 9 hours - and with the first block that Via mined, the transaction was confirmed.

[TheUltraElite]

Alright I guess I got misinformed about the functionality of ViaBTC and thanks for correcting me on that.

However I still dont consider the services provided about transaction acceleration by some members of this forum and like I said I would defenitely like to hear from them too instead of just giving it a one sided speculation. The last time we tried to ask CoolWave about it, SFR10 remembers it I am sure, it ended up being a childish thread in Reputation.

[sheenshane]

AFAIK, only 100 tx limits that allow per hour in the ViaBTC Bitcoin transaction accelerator.  If you will receive an error response it might be the 100 tx limit has been achieved within an hour.  Probably you should wait another 1 hour and accelerate the transaction next after an hour.

ViaBTC works quite normally all these years and does not work for those who have not read the minimum requirements, and do not know how to add a transaction.

Exactly, and here are the Bitcoin pools prove that they really work.
https://bitcoinchain.com/pools, and ViaBTC was in 4th place.

Yeah, acceleration in this case means including your transaction in upcoming block that will be mined by a certain miner. It doesn't have to be a miner or mining pool alone, it can be a service provider that has a contract with certain miners / mining companies, am I right?

And about ViaBTC, yeah, it works and is the first and real transaction accelerator that was created. There was a time when I could add a transaction on viabtc at any minute but right now, you have to add a transaction in milliseconds, for this reason it sounds almost impossible because of some people's reaction and internet connection.

Another choice is pushtx.btc.com but their fees are so high, it really, really doesn't worth to use them. Viabtc also has paid service, not good but better than btc.com at critical moments.

It is ok here, website and registrations work. Maybe you should clear cache and try again. This accelerator has replaced the Toxigon which was the free BTC accelerator year ago but later they deleted this function from website. https://ibb.co/kQvcVSd

Does anyone has experience with the mentioned accelerators?

P.S: I have used many BTC transaction accelerators but majority of the free accelerators are full of advertisement posts. I think using the Brave or ad blocking extension will be better rather closing the automatically popping up new ad tabs.

Most of the time when my transaction get stuck then i do make use of those free accelerator online which cant be sure if they are truly working or not yet you cant determine
if the said transaction had able to get confirmation just because it had been pushed through or simply it did really broadcasted.So theres no precise answer but some do say
it damn pretty works and as long i dont pay up something which is definitely a scam(lot of them online) then using them will dont put any harm.

freebtcaccelerator is just another broadcasting service and a buggy one, I've put a tx there as a test to see if they are offering me a paying confirmation service but I got the message that the transaction is already confirmed when it's not. Grabbed another one from the mempool and says the same.

The iraven one is doing the same, even their message is a hint:
"Successfully re-broadcasted transaction to the Bitcoin network."
Rebroadcasting is not doing anything, it might come in handy if the mempool goes completely overboard and transactions are getting booted out of the mempool but that's not the case. Actually in that case it would be better to simply let it be forgotten as it stands no chance of being confirmed soon anyhow.
