For checking the required fee to send a transaction cheap and fast, I'm using this one because it's very detailed and despite of that easy to understand. In addition the site offers different charts:

- Unconfirmed Transaction Count (Mempool)
- Pending transaction fee in BTC
- Mempool Size in MB

Mempool Size in MB is optimal to get an impression for determining the fee. If you are interested, here's more information about saving valuable BTC instead of wasting them for fees: Make sure to avoid wasting BTC for too high fees – step by step guide (Electrum)

And sometimes you'll see people paying way too much.  


(Someone paid a 0.1BTC fee for a single transaction)


Most of the other sites are recommending a very high fee while it's not really necessary to pay so much even if you want to have your transaction included in the next block.

Nice list.
I was usually using this website
https://jochen-hoenicke.de/queue/#0,24h

EDIT:

But I am switching to this one now:
https://mempool.space/tv

Thanks

[Pmalek]

I use https://jochen-hoenicke.de/queue/#0,24h as well.
Was a bit confusing at first trying to figure out what all the different graphs mean. You will mostly need the first and the third graphs that show the unconfirmed transaction count and the mempool size in MB. Basically the closer it is to the dark blue region the sooner your transaction will get confirmed and with less fees.

If you don't care to wait a bit longer just add 1 sat/byte and it will confirm once the mempool empties to that region.

Another +1 for Jochen's site. It tells you everything you need to know in a single glance to work out the best fee for your own needs. The best option.

A couple of the sites you have listed are poor recommendations. btc.com and bitcoinfees.earn both constantly and significantly overestimate fees. For example, right now the mempool is pretty much empty, and if I was making a transaction I would pay 1 sat/byte and be pretty confident it would be confirmed in the next block. Bitcoinfees.earn is recommending a fee of 16 sats/byte and btc.com is recommending a whopping 62 sats/byte. 62 sats/byte would put you 0.02 MB from the tip. Completely unnecessary and a massive overpayment.

If you can't figure out Jochen's site, then the next best site is usually https://coinb.in/#fees. You can ignore all the complicated sliders if you like and just look at the number at the bottom of the blue box. It will give you a much closer representation to what fee is actually required to be fairly sure of getting in to the next block, with massively overestimating like the two sites above.

Thanks a LoT. OP updated with this info.

Hey OP, just wanted to add here more mempool viewers and fee estimators

I am using the https://coinb.in/#fees, it is much newbie-friendly and simple user interface.
And btw in using the coinb.in, it is nice because you can manually set the inputs or outputs of your transaction, and also you can choose and set the transaction format you will use on your transaction then you will get the estimated/recommended transaction fee.

About the output setup, most of time it is set at 2. It is rarely to have transaction with only 1 input and 1 output. In contrast, we ususally have 2 outputs, one for receiving address, and one for a change address. You will have 1 output if you send all of your money from the input to the receiving address. If not, you have to set it with 2.

please remove this site or add a warning about it.
it should never be used under any circumstances because they are always suggesting extremely high fees and suggest it as "The fastest and cheapest transaction fee" which is a big fat lie.
not to mention that as far as mempool representation goes it is showing it as count (which is meaningless) instead of size.


for example right now they are suggesting 54 satoshis/byte for "The fastest and cheapest transaction fee" whereas mempool is almost empty a fee of ~3 satoshi/byte gives you the actually fastest and cheapest transaction. in other words they are reporting a fee that is 18 times higher than what they should have reported, and that's unacceptable.

[hd49728]

Something is wrong with https://coinb.in/#fees too. The suggested fee is 191 satoshis/ byte that is unacceptable too. I remembered recent days the fee has always been at 191 sats/ byte. It is probably the site has issues to update stats.

It you scroll to the bottom of that page, you can see that they are basing that recommendation on data from block 631174, which is over 2 weeks old. Trying to use the "refresh" button to fetch newer data also does nothing. Not entirely clear why it isn't updating like it should, but in the meantime, nobody should use or recommend it since the mempool is essentially emptying with each block and 191 sats/byte is a massive overpayment.

Or you can do custom (V1 or V2), base on your use case. There's always an option. mempool space/tv is version 2.

This bug has been long fixed. Their suggested fees are up-to-date again.
