The main thing to understand is Cryptic is a company looking to make money. Being the main driving force, all exchanges will benefit them more than us as players - P2P or F2P. Taking that into consideration, Cryptic needs to look at supply and demand factors. The need for dilithium has skyrocketed recently e.g. a special base project runs 200,000 dilithium.
As my fleet is less than 25 players this amount is way too high. It takes two days just to earn 1,500 myself and with the special projects switching so fast then only one is completed every few months. For fleets with more than 300+ players that number is feasible but keep in mind such a few number of fleets will reach that number.
So my basic analogy is they need to lower dilithium costs across the board or raise the amount of dilithium earned through missions and DOFF missions.

I don't know where you fall on Cryptic's statistical scale of 'how much dilithium people earn per day', but 750 dilithium per day on average seems pretty low to me. I only play my alt for about 1/2 an hour per day and I make the full 8000 per day.

I've got a lot of dilithium riding on the market bottoming out at 25. Crash I say!

Is that a typo as I can earn 1500 Dilithium in less than two minutes?

Unlikely, I think. Nobody would buy Zen and the thing would collapse.

But I have reasonable money on it settling in the 80-100 range.

FYI - in the Priority One audio interview posted today (Monday 11/5/12) - Al Rivera stated that when the new Reputation System goes live on Holodeck - the Rep Projects that y9ouo use to gain Rep for the various Tier will NO LONGER have any Dilithium Cost associated with them (they still do on Tribble atm.)

The Rep Projects you do to acquire actual gear and other actual character items still will though.

That's because you're not doing dailies.

• Officer reports gives 1440.
• Explore Strange New Worlds gives 1440.
• Chart the B'tran cluster gives 1440 (do explore at the same time to complete Strange New World).
• Aiding the Deferi gives 1440.
• Borg Red Alert Encounters give 480 each.
• The other two Deferi missions give 480 each.
• Traelus system gives 480.
• Distress call missions give 480.

If you only do the ones that give 1440, that's 5760 dilithium a day. If you do DOFFing, the 480 dil missions, STFs, and Borg encounters on top of that, you can easily max out at 8000 in just a few hours.
