Title: Is there a tool to accurate estimate unconfirmed bitcoin transaction?
Post by: mywaves on November 04, 2020, 12:14:55 PM
Hi,

My BTC transaction get stuck. I want to know is there any way that I can know when it will get confirmed?

My tx hash: 4054df5d554a3a1c4a05f8582d31449db69f0b80c8dda4d507f8b41d2e070fcb

Thanks.

It's pretty "simple"... First, check your transaction fee (in sat/vbyte). One of the easyest ways of doing this is looking up your tx on a block explorer:

you payed 1 sat/vbyte

The, you look at the current state of the mempool on a site like this one:

If you look at the bottom grahph, and you hover over the last couple of minutes, you'll see something like this:

A block can contain up to 1Mb of transaction data (not counting the witness data). You see that you should have payed a fee of >250 sat/vbyte to be in the top 1 Mb of the mempool.

You, on the other hand, are in the bottom 63 Mb... This means that IF everybody would suddenly stop broadcasting transactions, it would still take another >60 blocks before you'd have a decent chance of having your transaction confirmed...
~6 blocks/hours => >10 hours... and that is IF everybody would completely stop broadcasting transactions.

In your case it could take several days, even weeks or months before your transaction ends up in a block. There is no way of telling. Everybody who even attempts to give you a real estimation is basically guessing...

You didn't opt-in rbf, you payed less than 10 sat/vbyte, so if you want to speed up your transaction you'll have to pay a big mining pool (like viabtc) or execute a CPFP: https://bitcointalk.org/index.php?topic=5285192
