With Viabtc reducing slots, one free gateway to get cheaper transactions confirmed is nearly shut so in case fees go up again and you have one for those tx where you can't RBF or CPFP cause it's a tx between custodial wallets one might have to resort to paid accelerators.
Since I've been really lucky and during my 3 minutes check no block was mined to influence heavily the fees I tried to make a quick compare for two small one input one output, transactions so here you go, this is what one can expect for now!

But please note those are fees for next block being at ~40sat/b and the tx at 30sat/b! Tomorrow those might be irrelevant but at least you know the basic pricing.

TX A IS:  Size   ‎346 B/ Virtual size   ‎176.5 vB
TX B IS : Size   ‎294 B/ Virtual size   ‎135 vB

What I observed doing those tests:
- Viabtc offers free slots but has the highest paid acceleration fee
- Antpool offers tron payments, which is a bit understandable, if you can't accelerate your BTC tx, how ar you going to pay with BTC?
- Binance is the most annoying one, not only they don't show the charge in $ but also do this
https://www.talkimg.com/images/2024/01/06/sNGXD.png
discount, lol, what's this the fireworks isle after 4th of July to offer discounts? Really cheap marketing tactic!
- Antpool is the uncontested winner until mempool will be able to start their service for everyone

So it just seems as though Binance pool just happens to have its transaction acceleration fees are close to those of F2pool as possible.  I have a question regarding f2pool. How did you manage to get that much need referral code?

I'm not that familiar with binance's tx accelerator but it looks like it's being gatekept for the verified users? as I was asked to login to a binance account (same as the exchange) when I tested a transaction.

I think it'd be useful to make a note of this on the first post. Unless the user in question has a working kyc'd account in binance, it's def one of the deal breakers.

Yeah, probably the same model and the same internal pricing per byte, the slight difference might be just the seconds between my tests interfering with that, the few cents off are obviously because the price as the satoshis are the same.


Ok, so you need to be more specific about it, I have been on f2pool for years so I don't know this, do they require a referral code? I opened the page in a clean browser but it seems the registration is free?


Speaking for Binance alone, I though it was like a default thing, no way Binance would forfeit this opportunity to have someone open an account on it it and get his identity, but yeah, I'll update this tomorrow as I need to check what the others require also, I already have accounts on all those mining pools so probably it would be different for a new user.

You don't need to have a referral code for using their transaction accelerator and they allow everyone to use that.
Referral code is required, if you want to use their Push TX service (https://www.f2pool.com/pushtx). For pushing a transaction, you should submit the raw transaction in hex and that's a different service.

I think I now see two different transaction acceleration links

1. https://www.f2pool.com/pushtx
2. https://www.f2pool.com/user/tx-acc

Yeah, I registered an account, but for the first one, just below the box where you enter the signed raw transaction Hex, they require you to enter a referral code. Perhaps because the first one is a free transaction acceleration service?

I am seeing 0 sat/byte transactions (https://mempool.space/tx/67b61c6442d1fd70e4c8792883f0aedb48de3cb6c766e5c045ce9ddf4c539394) getting included in the block confirmed by them

Nice thread, It convince me further to enable RBF or at least set relative high TX fee rate.


FWIW if you use wallet with full RBF support, you can avoid paid accelerators. And if you're advance user, you can create raw TX with conflicting UTXO with higher fee and broadcast it to other node/explorer which support full RBF.

Never used it and it's the first time I clicked it, if it's labeled as push it should only do that, broadcasting the tx not a free acceleration service.
But the referral thing is weird, I'll ask around to see if someone mining there has one!


I don't know about that address in particular but things like this zero sat/byte one:
https://mempool.space/tx/dc4c8fef2a4500ea582aeb692542548f2f23205662ee87d5a16c83d41dcf3f4a
is f2pool paying out miners.


Bruhhhhh!!!!! Who the hell are you?  ;D ;D ;D Why the rebranding?
You dropped the ETF right now when everyone thinks one will get accepted? Some really bearish signs!

Anyhow, yeah, as long as you have some control you can still avoid paid accelerators, I would only use them if I do a transactions between to exchanges or some gambling site and the sender is an asshole and makes the tx with a fee that will never gets accepted, but even then I would till consider not doing a thing if he sends that with 10 inputs 100 outputs and 5sat/vb, I would rather let it drop than pay to accelerate something like that myself.

Requiring a referral code to just broadcast a transaction would completely make no sense, especially when there are other tools that can be used to do the same thing as well.

I picked that transaction from the list of their recently pushed transactions, there are other confirmed transactions in there which were at a lower fee rate compared to the optimal fee rate at that time like this one got confirmed 2 days ago and was at 3 sats/vbyte (https://mempool.space/tx/dc745e5838396e77c08dbaa3741c7abb7b03197106c8ad60376d01498048aebd)
So if it was just broadcasting, they shouldn't have been confirmed up to now.

There's a big difference between F2Pool push transaction service and other tools that can be used for broadcasting transactions.
Anyone who has a referral code can send a non-standard transaction directly to F2Pool, so that they include it in the blockchain.

I haven't suggested it's a broadcasting service. My observation tells me it's a transaction accelerator. Probably a free one and just has a separate link from the paid one that most people know. I don't see how both are different services as you suggested earlier on, except that one is paid, and the other requires a referral code to have the TX pushed.

Their push transaction service can surely act as a transaction accelerator, but that's not only a transaction accelerator.


I don't know whether their push transaction service is free or not.
They require users to enter a referral code because they don't want everyone to be able to use that service and I think that's because they allow submitting non-standard transactions.


Here are the differences.

• In their transaction accelerator, you should submit your transaction ID and therefore, your transaction should have been broadcasted before using other tools and they should have your transaction in their mempool. In their push transaction service, you should submit the raw transaction in hex and you send your transaction directly to F2Pool.
  
  
• In their transaction accelerator, you can't submit a non-standard transaction, but in their push transaction service, you can submit even a non-standard transaction.

Guys are not even replying towards what I see here, and one thing peculiar to all these acceleration services is that they are merely ripping people off their money, the monopolistic system of Bitcoin in favour of the miners is too much and gives room to such. No wonder they will never pray for the network to be at peace so that they can only honour the high fees and make life miserable for Bitcoin users, especially those whose transactions are stuck and who still would want to use the accelerator service but will be discouraged by even a higher fee. This is madness if people are not so concerned about it.

This is entirely a business for them, they don't care about anybody or the network, a system of win-win deal for these guys in a situation where there is no good option which makes it so annoying. Nowhere to run to by common guys who are not rich but I don't think this is what Satoshi wanted for the network/system. They've taken hold of this system back to back, milking deeply. It is so sad.

Complain about the people making ordinals transactions and causing congestion in the network, miners are offering a service to the BTC community and they have to be paid for it. They mined tx's when the fee rate was ~ 1-2 sats/vByte, and you can't complain now that fee rate has gone high, which by the way is no fault of miners.
Mining is a business, miners buy gears, pay for electricity and maintenance, all of these cost money. It is worth mentioning that miners do not fix the fee rate in the network, so i am shocked how people try to blame miners. Satoshi wanted a free network and that's what we have, anyone can buy gears and become a miner, anyone can also attach any amount they want to their tx, but if others outbid you, then you have to wait.

I have experienced using Binance acceleration with one of my transaction that has stucked for a long time, I have to do it since I just wanna try it out and it charged me like $20 for the acceleration. The website is directing people to their telegram contact and that's how I contacted them and gave my TXID and it has estimated how much I need. I just obliged since I've been waiting for that transaction to get confirmed for a very long time, you won't believe it because I made a mistake for broadcasting it until it didn't hit the fee that I've set. I'm not sure if I'll use them but did helped me though.

I can't wait till there will be no block reward and nobody wiling to pay fees in a protest to these evil miners!
Love how everyone wants cheap fees, fast transactions, security against an attack, whole decentralization, but at the end of the wishlist it's still willing to pay one cent and not a penny more.  Btc() com lost 2.6 million last year, riot went into bankrupcy protection, nobody cared, but god forbid they would make money out of this after putting in million.


Well everyone is free to mine without making it a business.
So the community will simply need to buy either the business of those mining farms or build their own by ..investing $9 billion in 3 million S21 and some 9GW, then the chain will run on something that is not a business consuming unicorn farts as it's mining blocks!


For real? It's not fully automated?

Before it wasn't like that image that you've posted when you just have to paste the TXID and it will calculate the fee. I didn't see that process several months ago so maybe it was already updated or I just can't vividly remember if it was there.

But this was the process that I was able to encounter when I've used them, it was manual. I've messaged on that telegram account based on the instruction they have for mining/acceleration and they were the one to estimate how much I'll pay as they replied back.


I can't find the message or the conversation that we've got on Telegram, maybe they have deleted or cleared the history already. There are the other steps from step 1-4, my memory isn't so good nowadays but prolly I just shortcut and jumped to step 4 but it did worked.

Cheap marketing? Huh. I assume, highest percentage of smart people make RBF-enabled transactions, so, there you have a majority of people who have no idea about RBF and correct transaction fees. This marketing is aimed towards those people to give them a false sense of discount and motivate them to accelerate transaction on Binance immediately.

I remember, Binance had a different payrate for VIP members according to their VIP level but I checked it right now and there seems to be only one rate for everyone.

Not related to this but how is that some transactions are full-RBF enabled while actually sending from a non-rbf enabled wallet?

I used to just rely in ViaBTC's free accelerator for some of my transactions just a few weeks back. It's a shame that they feel the need to reduce the slots in the free service and move forward with their paid accelerators.. Oh well, they have the machines anyway.

I currently rely on Samourai Wallet's RBF feature. So far I don't feel the need to use it, because I've been overpaying my transactions ($7.54 from a transaction 3 days ago) just to make sure it gets confirmed and not lost on limbo. Binance's accelerator is good, too, but like what other users have mentioned, the requirement to have a KYC'd account with them might deter other people from utilizing the said service.

Antpool it is, for the meantime. There is also BitAccelerate (https://bitaccelerate.com/) for those who wants to take a shot in using a free accelerator service. Though with my experience on this service, they aren't as quick as ViaBTC or Antpool's.

Full RBF is a setting for nodes. If a node has enabled full RBF, it treats all transactions as RBF-enabled and accept the replacement transaction, even if the original transaction has not flagged as RBF.
If you have a non-RBF transaction and you want to replace that with a new transaction, you should broadcast your transaction from a node that has enabled full RBF.


Bitaccelerate don't accelerate your transaction at all. They only rebroadcast your transaction and that's different from accelerating.

I really don't understand why some still use BitAccelerate it says there clearly:

it's a rebroadcast system, if your tx has such a low fee that it's going to be purged by nodes then there is no chance in hell it would get confirmed, it would be at least 100 block under , so what's the point? Actually since they don't ask for a fee, what's the point of that website also? Not going to disable adguard to check but other than income ads and donations I really don't see a reason for its existence!


Yeah, cheap marketing!
Because it's not a product on a market , it's not like you're offering a pepsi bottle 50 cents cheapen than the shop next door, it's not like selling a phone that was 1000 yesterday for 900 now! It's a sum that fluctuates according to the mempool congestion, so saying you offer a discount to a non existent prior price is just garbage!

It seems that they themselves don't know what accelerating means and how that's different from rebroadcasting.
Their website name suggests that it's an accelerating service. They say "BitAccelerate is a free Bitcoin transaction accelerator" and then they say "Our service will rebroadcast the transaction via 10 Bitcoin nodes."

It used to be 100 free accelerations per hour. Did they reduce it? The browser I am trying to load the site is giving an error and the data are not loading to check it myself.

It is true. I once tried their paid acceleration and I was frustrated. The paid acceleration fees are not reasonable.

Down to 20! Also don't try to refresh it too much, you'll get an autoban, especially if you're on a VPN.

And you nee to paste the tx after the 00:00 and hit the button, it doesn't count like before the moment you solved the captcha, so you can't have it all ready by the exact 00 and just then press the button. You need to both paste the tx and solve the captcha after that, if you're not on a desktop and fast internet you have no real chances, just the loading time on my mobile (on 5G) is a turn-off.


If ever needed, use antpool!
I randomly picked a 1 input ~100 output tx out of the mempool and the resultsa re liek this:
Antpool:
Viabtc:

Of course it's bigger than what you probable have but it's still 300% more expensive!

It's now sitting at 20 free accelerations per hour, a far cry from where we're standing before. I never really got the chance to use it again since I last used it on the 29th of December since bots are always at it taking the free slots.


I went and checked a stuck transaction (https://mempool.space/tx/54fa3193d2407b0fd384cdb7643799a8436ef09db112d17ca3a2c93fe1900b2d) I have for 3 weeks (though stupid on my part, I tried adding that dust into the transaction) and was amazed that they were asking $108 worth of crypto to accelerate the transaction. Mempool.space offered about $20 to have this transaction pushed, but perhaps I'll just wait until this whole Ordinals thing is done, or still keep trying free accelerators to see if I have any luck with them.

I don't even try to use ViaBTC free accelerator anymore, the chances are just slim to none and since fees are not so high right now, i just pay the appropriate fee.
The fee rate attached to your tx is 16 sat/vByte, i think it is going to be a long time before fee rate in the mempool drops to that level. However, the ordinal spammers have taken a little break of late and that is why tx fees have dropped and i don't know if we are going to see an end to this anytime soon.

Yes, right now everything seems to be pretty calm, especially in the afternoon in the West. Since I got this stupid transaction out, I made sure that I am paying the right fee and not including any dust outputs. Crazy how I was able to get a transaction with a very low amount just a few months back, and now I have to refer to mempool.space to check what is the most economical fee I could pay to get transactions going :D


That's stupid on my part to include dust on the transaction. Even ViaBTC's free accelerator won't accept this transaction in their service. It may even take a month or two before this transaction gets confirmed, or I might have to accept defeat and get a paid service accelerate it for me and just blow whatever remains of that $100 transaction.

You don't have to use an accelerator for your transaction.
The fee rate you used for your transaction is below the purging fee rate of any node with default mempool size. This means that there are many nodes that don't have your transaction in their mempool.
You can import your wallet into electrum, try connecting to different servers until you find a one that doesn't have your transaction in its mempool and then make a new transaction.

Since ViaBTC's free accelerator doesn't work anymore I tried to use Antpool's paid accelerator yesterday.  I didn't have any USDT so I waited until I could make an exchange today to try again but they have now changed the minimum cost you have to pay for an acceleration to $50.

Bitaccelerate recently launched a premium acceleration service although there aren't much details on which pools they are partnering with.
https://bitaccelerate.com/premium

The thing is, this wallet is Bitcoin Android Wallet which cannot be imported to another wallet as far as I know. I tried looking for other methods to import the private key to another client but with no luck. I was already on to it when I realized I screwed up but lo and behold, this particular wallet is a hermit that does not want to outgrow its own shell, hence why I rely on rebroadcasting the tx and looking to get it accelerated for a fee eventually.

EDIT: This has since been resolved. I managed to follow the steps in this topic (https://bitcointalk.org/index.php?topic=5305923.0) and restored my wallet to Electrum.

At least their price per vb seems to not have moved, so it's just that they are not really interested in little payments anymore, any larger tx would anyhow go voer the limit.
At 30sat/b they charged 22.15 USDT for 177 vBytes 
At 35sat/b they charge 58.30 USDT for 622 vBytes


Hmmm..they change Fiat amount: $186.00 for what antpool charges $60 so , combined with this:
u get the idea  ;D

How have you then cope with the time when the transaction fee were high, don't you make transactions or you just deliberately avoid making transactions.


Maybe we should expect this to last for now while we expect something to serve as a lasting solution to high transaction fee, honestly I don't like it to have bitcoin as something that will be unaffordable by many to make transaction, but with the help of mempool and the viabtc, we could achieve something fare as transaction fee.

I used to get a lot of luck when the slot for ViaBTC's free acceleration was 100 and when bots had not taken over, but now i don't even try because the chances are so low. Right now the fee rate is not as bad as it was, you just have to make sure not to accumulate too many inputs and if you do, use coin control when spending to reduce the number of inputs.
Nobody likes it that BTC has become unusable as a payment option, and people now use it when they have no choice but to make the tx.
