Title: I made a simple realtime page for mempool size and fee estimations
Post by: spookiestevie on June 23, 2019, 10:20:15 PM
This is my first post on BTCtalk :D
I made a simple realtime page for mempool size and fee estimations.

You can get a good idea of how long it will take a transaction to get 1 conf with a combination of the current sat/byte fee rate and the number of transactions in the mempool.

Sometimes I like to spend time optimising my transaction fees to best suit my time preference as well as the fact that I don't have much bitcoin to throw at miners (sorry not sorry). :P

Check it out, feel free to give feedback, thanks!

For the fee estimation, are you simply retrieving the data from bitcoinfees.earn.com because the estimation seems to be the same, or you're calculating it yourself? Regardless though, I suggest working on that because coinb.in is far more accurate and also cheaper (from experience).

Yeah, your fee estimations don't seem very accurate at all. At time of writing, your site is suggesting:

Fastest: 72 sat/byte
30 min: 66 sat/byte
60 min: 50 sat/byte

Looking at the third graph here (https://jochen-hoenicke.de/queue/#1,2h), both 72 and 66 sat/byte put you with 0.5 megabytes of the tip, and so are both likely to be confirmed in the next block. 50 sat/byte puts you within 1 megabyte of the tip, and could also get you in the next block, but probably within 2 or 3 unless the mempool sees another spike in activity.

As OmegaStarScream says, bitcoinfees.earn.com is notoriously unreliable and grossly overestimates the required fees.

I like the whole idea, especially since the suggested fees are now very significant. But I would also like to know how you make these estimates and how likely they are according to your views. Do you use this data, for instance: https://jochen-hoenicke.de/queue/#0,24h? And how do your website's estimates differ from, say, bitcoin fees calculator: https://www.buybitcoinworldwide.com/fee-calculator/?
I remember that there has been a situation before when the recommended fees were too high, and basically there was no need to actually pay that much, especially since so many people were paying that. But I usually don't risk to experiment with fees and simply pay what blockchain.com tells me to pay. If there was a way to pay less while being strongly sure that it won't cause serious delays, I'd be interested in that.
