I like this one as well: https://btc.com/stats/unconfirmed-tx
The 2nd gives a really good indication of "where" in the fee stack all the of transactions are sitting... by looking at the number of bytes on the right, you can get an idea of how many blocks of data are at/above any given fee value.
You need need to gauge the network activity, and how many transactions are likely to be added in before the next block is found etc.
Then there is this "rainbow": https://jochen-hoenicke.de/queue/#
Lot's of data, once you figure out what the charts are actually telling you!
Awesome links, thank you very much!
My transaction is at 128 sats/byte so if I read the chart correctly the estimated time is between 55 and 1440 minutes. Quite a range lol. I'll be curious to see what it ends up being.
