For some reason ViaBTC's accelerator has not been working since I tried it yesterday - tried numerous times to accelerate my transaction, straight on the hour, in the very first second of a new hour - Submissions are beyond limit. Tried 10 more times - same bullshit.

I have used their service lots of times before, and there was never an issue as long as I did it straight in the first few seconds of a new hour.

What the fuck? Has anyone had any success using their service in the past day?

On a related note - can anyone accelerate my transaction, please? The TX ID is https://blockchain.info/tx/2727e9d1517770c0e6a616cbff5544251559b10924b329a14a90a1f2fac61ed0

Many people use it, so the 100 transactions per hour fill up very quickly.

You should avoid small transactions, your 0.00048874 BTC (https://blockchain.info/address/1AbFgqf5Ng7teeHYvjqjzrettq9w9jGPrs) output for instance is smaller than the fee required to use it again. Basically, it's worthless dust at the moment.

That's a transaction a customer sent to me - it wasn't me that sent it.

I know the 100-per-hour transaction limit of ViaBTC fills up very quickly - I have tried like 10 times already, ALWAYS on the hour, ALWAYS in the very first second of a new hour ( I have made sure my clock is synced properly ) and I literally watch the clock hit the 12 mark and press "Accelerate" - always getting the "Submissions are beyond limit" bullshit.

Never had that happen before, and I've used them numerous times. Yes, if I am like 5 seconds late, it's already filled, but that's normal, I guess.

I have.


It is possible that your system clock and their system clock are not set exactly the same.  So, by the time you think it is "straight on the hour", their system might have already been accepting transactions for many seconds.



How do you know that your clock is synced to their clock?

When I'm trying to help someone out and accelerate their transaction for them, I typically start trying to use viaBTC about 3 or 4 minute before the hour. Then I repeated try over and over until it either succeeds or until it is 3 or 4 minutes after the hour.  If I miss the window of opportunity (because I'm too slow entering the captcha), then I try again the next hour.  I've never had it take more than 3 hours of trying before being successful.

Yeah, I've thought about that.

But it was never a problem before - so I assumed our clocks are synchronised in the same manner.

I will try your approach in about half an hour - the captcha is a bugger and I hope it doesn't trip me up, especially if it displays characters that are tough to recognize and quickly type up...

I don't get why this backlog of unconfirmed transactions keeps growing and growing - it's at almost 185k already. Seriously, WTF?

When is this junk with a huge unconfirmed backlog gonna be permanently fixed - lightning network and whatnot? This is getting ridiculous, geez...

Send me the txid, and I'll try at the top of this hour as well.  That will double your chances of success.

Appreciate it - TX ID is 2727e9d1517770c0e6a616cbff5544251559b10924b329a14a90a1f2fac61ed0

I tried.  Was unsuccessful.  Hopefully you had more success.

Note that if you are a viaBTC customer, you get the ability to accelerate transactions a number of times with no limit on the number of accelerations per hour.  It's pretty expensive, so it generally isn't a worthwhile solution unless the transaction you are trying to accelerate is a LOT of money.

I think they give you 5 accelerations for every "mining contract" you buy directly from them on their "cloud mining" service.  1 BTC contract currently costs about 0.1103 BTC, so the 5 accelerations would cost you about 0.02206 BTC each.  In theory, over time, that cloud mining contract would earn you back a portion of the 0.1103 BTC that you spent, so the effective cost would be a bit less.

I tend to assume that most cloud mining is just a scam, so I would never purchase a viaBTC contract with the intention to profit from cloud mining, but I have purchased a contract from them in the past when the contracts were a bit cheaper and I really needed to accelerate a transaction.  Back then the contract only cost 0.097, and I have since "earned" back 0.055 BTC from "cloud mining".  So the effective cost of the 5 accelerations turned out to be 0.0084 BTC each.

I also try yesterday few times and it is not working no matter how accurate I try to be in submiting transaction.So maybe they temporarily shut down free accelerator or someone found the way to take advantage of all the possible accelerations available every hour,maybe with some script or something like that.

Considering how big problems users have with high fees and stucked transaction,for some users such service become a lucrative business.

They cannot automate that with a script - that's what the captcha's for.

Also tried on the hour and no luck again.

I just decided to check out the transaction on various block explorers besides Blockchain.info, and it doesn't show up anywhere else. What. The. Actual. Fuck?!

The fee isn't that low, geez, it's 60 fuckin sat/b.... Why isn't it showing anywhere....

TX id: 2727e9d1517770c0e6a616cbff5544251559b10924b329a14a90a1f2fac61ed0

Character recognition has advanced to a level where automated services can have a significant success rate.


Sorry to hear that.  Hope you get through soon.

There is a huge backlog of unconfirmed transactions right now. I suspect that there are probably more than 100 people that are all trying at the exact same time.  Under these circumstances I'm not sure which method will be better (your method of clicking the "submit" button exactly at the top of the hour according to your own clock, or my method of repeatedly trying from a few minutes before until a few minutes after the hour). If there are 1000 people all trying at exactly the moment when viaBTC resets, then each user will only succeed an average of one out of every ten times that they try.  If there are 10,000 people all trying at exactly the moment when viaBTC resets, then each user will only succeed an average of one out of every hundred times that they try.

On the other hand, the more times people fail the more likely they are to give up trying, which may increase your chances as long as you stick to it.

Good luck.

Not sure.  However, you can push the transaction directly to viaBTC to make sure they have it in their mempool.  If they don't have it, and you manage to time an acceleration correctly you'll get an error about it being an unrecognized transaction ID. It will be VERY frustrating to finally get the timing just right, and have it fail anyway.

You can push the raw transaction to their mempool here:
https://pool.viabtc.com/tools/BTC/broadcast/

Please don't hijack someone else's thread. Your post has been reported to a moderator.

Appreciate the continued help, Danny - how can I push a raw transaction to their mempool, that was apparently sent via the Blockchain web wallet?

You can get the raw hex transaction from blockchain.info with this link:
https://blockchain.info/rawtx/9a2a0b1ba7949447acfba20829b1eda303828f172b1bbbf3c11101f9b7670b61?format=hex

In case you ever need to find the raw transaction at blockchain.info yourself...

Just change the usual /tx/  in the URL to /rawtx/  and then add ?format=hex to the end of the URL.

You can copy the transaction from there, and then paste it into the text entry box at the viaBTC link I provided.

Awesome, been outside and just got back home - already submitted the raw transaction and will keep trying to push it to accelerate tonight.

Thank you so much!

When the "recommended" fees are over 500 sats/byte... "60 fuckin sat/b" may as well be zero sats/byte :-\

Especially with 100,000+ unconfirmed transactions floating about in the mempool...

Looking at https://btc.com/stats/unconfirmed-tx we can see that currently there is at least 72 megs or roughly 72 blocks worth of transactions that all pay higher than your 60 sats/byte.

At an average of 10 minutes per block, it would theoretically take 12 hours for all those transactions to be confirmed before yours... But only if no more transactions were added. Each transaction that gets added from now that has a higher fee, is effectively shunting your transaction further down the queue... And delaying confirmation of your transaction.

I'm personally wondering when the point will arrive that you'll get faster confirmations by simply mining your own block with a GPU ::) #onlyHalfJoking

I've noticed some strange activity in the Bitcoin Mempool, seems like there is an ongoing Tx spam attack thus delaying normal users deposits/withdrawals.

I put my money on Bitmain and the BitcoinCash guys taking aim at bad boy Bitcoin.

After watching tone vays on the mem pool.  I seriously doubt this is normal.  This is all cause of bitcoin cash imo.

Anyway my transaction has been stuck for a day.  I'm going to try again, but maybe some one can help me out.

Thank you

Hi Guys, congratulations for having tx confirmed, anybody can help me with this transaction ?

I am clicking on ViaBtc without effect still got "Submissions are beyond limit. Please try later." Danny Legend can You try ?

Please help

Happy New Year !

A couple weeks ago you could get on the site and accerlate at the beginning of each hour.  Now it's not working.  Don't know if all their slots are used in their paid section or what?

Now it is not working on the each hour basis also bro. Today I have tried accelerate the transaction of my friend but unfortunetely when I am tried to do that it takes me to the different site from that page.
I am not sure what is wrong in that page and paid service seems working like before as well.
What is the problem in the site guys. I can still have a good experience with the antpool accelerator.

It's working, but in some time frames there are so many individuals trying to accelerate their transactions, that it basically results in a situation where like thousand people battle to get one of the hundred hourly accelerations. To add; these people also have to battle against those who run scripts, which more often than not are making money from it. That's why you see them always state that your transaction will confirm within x number of hours, and never exactly within two hours for example. It will leave them enough room to gain a spot in ViaBTC's accelerator if the first attempts don't work out.

No luck for me... I try every hour 8 times still got "Submissions are beyond limit. Please try later."

 :'( :'( :'( :'( :'(

It's same for me, and that last for weeks already. Go yo service section, there are couple guys that can speed up your transaction for free, they have daily limits so you can't speed up all your transactions without paying, but for one everyday you will not have a problem I think.
ViaBTC was good site in the beginning, but they are slow for some time and I don't try to speed up transactions there, try with my advice that can solve your problem for now.

Same experience on here even how I tried to wait for the very first second exactly on where the counter restarts.I do still failed up to push up transactions just like on what OP saying here those alerts regarding beyond limit is still repeating which I didn't tend to go further and rather just giving a shot on those free services or pushing up transactions on those guys on services sections. I don't know if it does work but did give a try and luckily someone did able to push my tx.

I tried there several times with no luck. There seems to be a tool, which provides you the exact full hour. I use now a paid service with success (not VIABTC). And the transfer fees seem to be moderate at the moment.

Please include this is for charity purposes.

I will be very grateful for help, very worried about the translation ::)

Do not waste your time mate. Create a account on antpool and try to use the proirtize acceleration option there. There you no need to faster posting on acceleration like you do on viabtc accelerator.
In viabtc first 100 transaction only without payment I guess. After that all the other transactions are paid service one only.
Better you can antpool accelerator for free transaction acceleration.
