Well, that would be it. Thanks for answering your question!

To answer it further, miners do often accept only transactions with high enough fees. I expect this to only increase around December, when the non-fee block reward is halved. The clients, other than spam prevention, do not preferentially forward as far as I know.

Why would a miner waste time adding transactions to a block for a reward of essentially nothing? in fact one can argue that it wastes resources. Miners aren't in it to be nice to others, they're doing it to make money.

Again this is question from 2012 when blocks were still empty and nobody cared about the fees very much and most money was from the rewards. (It only bubbled up, because I added up the note.)

I am developing a Bitcoin application, so I am sending a lot of "toy" transactions for testing, with 0 fees.

But it seems that those take *forever* to get confirmed. (Right now I am waiting 45 minutes for one transaction to get confirmed. Previously it was about 30 minutes.)

Is my suspicion right, or am I doing something wrong? How important is the fee for miners? Do they preferentiate?

Or am I doing something wrong (not broadcasting to enough nodes, maybe?)?

And do *nodes*, that aren't miners (with official client I presume), preferentiate to send around transactions with fees?

The relationship between fee and confirmation time will change over time.

This chart provides a view of confirmation time for "fee" and "no fee": <http://bitcoinstats.org/>

However, the chart gives no information on the size of the fee paid. I'd like to see charts of:

1. Fee Paid vs Confirmation Time
2. (Transaction Size divided by Fee Paid) vs Confirmation Time.

Both these, especially the latter, are likely to show a stronger trend than the link I provided above, if/when we start hitting the size limit for blocks.

If anyone finds a site generating one of these, I'd appreciate it if you could provide a link!
