-snip-
Is there somewhere a statistic chart showing this for the last months?
I see that you've moved this specific question from your other topic into its own thread.
I already got an answer in that thread, I'll quote it here if you missed it:
-snip- you can select another slider option in the drop-down menu of the 'send' dialogue box:
From 'ETA', 'mempool' and 'static';
- ETA: the default with most accurate estimate (but most of the time over-estimates)
- mempool: for advanced users who can understand how mempool works; usually, it's "1~0.5 MB from tip" as the 'express' fee rate.
- static: the basic slider with pre-configured values from 1~300sat/vByte.
The absolute fee is displayed above as "
Mining fee", but the prioritization is based from the "
fee rate" (
slider).
Why do you have to calculate and research just to send a transaction with "
necessary transaction fee"?
Your wallet already got that covered so you don't have to go to web for statistics and calculate in order to find the optimal fee.
Amongst the options, I'd suggest you to use "
mempool" and use
1~0.5mb from tip (
displayed when you hover-over the slider).
Personally, my technique is: Open the 'Advanced' tab, set the fee rate slider to '1mb from tip', then edit the absolute fee by a few satoshi higher so it'll be just below the tip.
Overall, no can can really estimate if the next block will be mined quickly after you broadcast the transaction,
the mempools can grow in size during that time making your "
optimal fee rate" drop out of the priority.
