1 sat fee

[CrypticAce]

how long would a transaction like this take?

21.co's Fee Estimator current estimates that it will take 0-5 blocks (and 0 to 90 minutes) for it to be confirmed. However it is only an estimate and it could take longer/shorter, and you never know when the next network spam attack will happen. Any specific reason why?

If you have a transaction 'stuck' send me the transaction ID and I can get AntPool to add the transaction to one of their blocks to get it confirmed.

Probably three weeks from now it will be confirmed. That is the most optimistic estimate with non-segwit addresses. Adapt segwit and it will  be two hours.

It may takes a little longer, i guess more than a week especially when there are so many stuck transaction in blockchain or worst it may never be confirmed because it will be treated like a zero fee. Why dont you try it to yourself by sending bitcoin using a little amount and lets see whats the result of it.

It is a pointless test... prior performance is no indication of future performance.

There are too many variables at play to say that an X fee will confirm in Y blocks/minutes/days etc. We've all seen the way that the number of transactions suddenly spikes at random times. If you send using 1 sat/bye fee when mempool is empty, it'll likely get confirmed next block. If you send it when there are 30,000 unconfirmed transactions all paying 100+ sats/byte, your 1 sat/byte transaction would like not get confirmed for days.

At the end of the day, if you want to cheap out on fees, regardless of how busy the network is... use a fee of at least 10 sats/byte and use the "free" transaction accelerators like ViaBTC or confirmTx etc... works for me

Yes, TX accelerator are the best chance for you if your TX is already brodcasted

What's the idea behind free tx accelerators?

What's the idea behind free tx accelerators?

Free TX accerelator was made to include a TX with an appropriate fee (not a low fee) manually to the next block of the X mining pool in order to give people the priority they need instead of spammers in the bitcoin network. These tx accerelator just needs a human verification (e.g. captcha). There is also ViaBTC - a mining provider - who is handing out free accerelation when they buy its cloud mining hashpower.

Nice explanation. Thx. I was wondering about the very same question. Does it mean that the low fee transaction sort of leeches it self on another transaction with a higher fee?

Well, for example:
The network is under a heavy spam of transaction and the fees are climbing to 300 Sat/byte. Peter sends a transaction with 100 Sat/byte fee whereas Jessica sends a transaction with 140 Sat/byte fee.
Peter uses one of these free accelerated and accelerated his transaction which has 100 Sat/byte fee successfully. On the next block, Peters transaction got confirmed while Jessicas transaction is still unconfirmed.
How does it happen? The mining pool specified that this transaction has a higher priority for his next block than other transaction.
This is just an example but in this way works an acceleration. These free accelerator doesn't accept in fact transactions whose fee is 1 Sat/byte or 50 Sat/byte, the mining pool wants to get a piece of cake and not nuts as a reward.

That's not true... ViaBTC has a minimum of 10 sats/byte (or 0.0001 BTC/kB). 50 sats/byte is way more than required by ViaBTC:

Why does it say “Transaction does not exist”?
In the following cases, you may be told that your transaction does not exist:
1) Too low fee: We only provide accelerator services for those with at least 0.0001BTC/KB transaction fees;

confirmtx.com only seems to require that your transaction is UNDER 500 bytes... and they're accelerate it for free... I've no idea if their service actually works or not, I have no real way of confirming whether or not a transaction was confirmed because of their actions or just random luck. At least with ViaBTC you can see if the block your transaction was included in was mined by ViaBTC or not

Yes, it was just an example, it could differ from the accelerators conditions.

Wow, wait does that work? The tx confirmation website. I'd heard about individuals providing this service, but I thought it was a scam since I didn't know that you can single out transactions to confirm. Thanks for the tip.

But what's their incentive? If miners want to include free/low-fee transactions, why don't they do it automatically?
Unless the idea is to avoid blockchain spammers by requiring a captcha.

Bitfury does, or did do it automatically. By requiring someone to go to a website, it's nearly free advertising for them, makes them look like the good guy and it prevents spammers from getting in their low fee spam easily. It also lets people who need a confirmation really urgently get priority over others, since those that might be just consolidating their inputs might not be in a rush. They also offer a paid acceleration service, and some users of the free service may opt to use the paid one so it's easier for them to get their transactions confirmed.
