High Priority Transaction with Recommended Fee Unconfirmed *22* Blocks

[BookLover]

Oddly enough though if I have adequately "aged" UTXOs I can send txs (that involve a large enough BTC amount) with *no fee* and they will appear generally in the very next block!

priority = sum(input_value_in_base_units * input_age)/size_in_bytes (source:https://en.bitcoin.it/wiki/Transaction_fees#Technical_info)

Input age (number of confirmations) and number of coins sent have a huge affect on transaction priority. (assuming the pools haven't changed the relevant settings too much.)

Although I know the input age makes a big difference mining pools don't necessarily follow the "standard rules" when it comes to tx inclusion (so although pleased I was actually a little surprised that zero fee well aged txs are seemingly always preferred over adequately aged txs with the minimum fee).

To my thinking the pools would always prefer the txs with fees than those with none (and no-one can force them to include a tx).
