Bitcoin transaction guides
Everything we learned building a free accelerator, written down plainly. Every number here was measured from live network data, and re-measured every morning, not copied from another blog.
There are ten guides here and they answer three different questions. If your transaction is stuck right now, start at the top. If you want to understand why it happened, the middle set explains the mechanics. If you are deciding whether to pay somebody, the last set has the measurements.
Start here
Bitcoin transaction stuck? Here is what to do
Five causes, ranked by how often we see them, and the fix for each. Most cost a few hundred satoshis and none need an accelerator.
How long does an unconfirmed transaction take?
Real timings by fee rate, the 14 day expiry explained properly, and why the 72 hour figure everyone repeats is wrong.
Bitcoin transaction disappeared or not found
If no explorer can find it, the network never had it or has forgotten it. The coins never moved. Here is how to put it back.
Confirmation taking hours? What each hour means
One hour is usually a slow block. Six hours means a low fee. A day means it will not confirm by itself. The decision at each stage.
Bitcoin transaction not found: what it means
The exact wording on each explorer, the five causes in order of likelihood, and the one case where you need to act.
Bitcoin transaction failed: what it means
Seven different events wear the same label. Which one you have, where the coins are now, and what to do about each.
The fix
Replace-By-Fee, step by step
Every unconfirmed transaction is now replaceable. What a bump really costs, and the exact clicks in six wallets.
Child Pays For Parent (CPFP)
The fix when you received a slow payment and cannot replace it. With a worked example and the Core 31 cluster rules.
Exchange withdrawal stuck: Coinbase, Binance, Kraken
You cannot bump what the exchange signed. Three real options per platform, and a warning about the fake support numbers on these searches.
How to push a Bitcoin transaction by hand, with the raw hex
Where to copy the raw hex in Electrum, Sparrow and Bitcoin Core, four endpoints that accept it, and the exact error strings nodes return with what each one means.
Push a Bitcoin transaction: what it does
One act, four names. What a push fixes, what it cannot touch, and the exact reply every public push endpoint gives.
Can you cancel a Bitcoin transaction?
Yes, while it is unconfirmed, by replacing it with a payment back to yourself. No, once it is in a block. How, what it costs, and the wallets with the button.
The market
Why the mempool is full but fees are 1 sat/vB
A huge backlog and rock bottom fees at the same time. What Core 29.1 changed, and why that queue never drains.
Do Bitcoin transaction accelerators actually work?
We pulled the public acceleration records and the live pricing. Paid acceleration is real. The median buyer did not need it, and quotes run 3 to 17 times the actual shortfall.
Bitcoin accelerators compared
We checked every service the listicles still recommend. Several are dead, including two of the biggest names.
Bitcoin accelerator scams: six red flags
Never give a seed phrase to an accelerator. Six flags that separate a working service from an advance fee scam.
ViaBTC free accelerator in 2026: does it still work?
ViaBTC only accepts free submissions paying 0.0001 BTC per kB. On the day we checked, not one waiting transaction paid that much. Here is what that means for yours.
Paid Bitcoin accelerator reviews 2026: what you really get
One real stuck transaction, quoted by every paid accelerator that still works, next to the cost of fixing it yourself. The cheapest purchasable option was about thirty times the shortfall.
360 Bitcoin Accelerator: what still works
The free tool is switched off, the $25 paid option rebroadcasts every 15 minutes, and neither can do what people pay for. Checked on the live page.
ViaBTC paid accelerator, priced and timed
How the paid tier is priced and paid, the no refund rule, and what ViaBTC's 9.4 percent share of blocks means for the wait.
The mempool accelerator: cost, pools, live quote
How it works, the fifteen pools it reaches with their block shares, a real quote on a 0.10 sat/vB transaction, and thirty days of its records.
The best Bitcoin accelerator in 2026, ranked
A straight ranked answer, the five tests behind it, and the live status of every accelerator the listicles still recommend.
ConfirmTX accelerator review 2026
HTTP 522 on every check, a Trustpilot notice that the website has closed, and listicles that still rank it. What happened and what to do if you paid.
