List of dilithium rewarding missions

Let's have a discussion about how to farm dilithium quickly and efficiently. Here are a couple of my personal tips and tricks that I use:

• Since I don't play every day, it's possible for me to "save" daily missions. The 20 hour cooldown timer for daily missions begins when you accept the mission, not when you complete it, so it's possible to accept a daily, wait 20 h, then complete the same daily twice in a row for double the rewards.

• Join the REDALERT channel for real-time Borg alerts. If you are Level 50 and have decent equipment, a Borg alert takes about 10 ~ 15 minutes to complete and rewards 480 D.

• The "Investigate Officer Reports" daily rewards 1440 D each time it is completed. Quick foundry missions are made by The_Grand_Nagus. For Federation, they are called "Distress Call" and "Prisoner Transfer", and for KDF they are called "Shipyard Defense". This daily takes less than ~10~ 30 minutes to complete if you use these special foundry missions.

• Combine "Explore Strange New Worlds" with an exploration mission. If you are Level 50, combine this with ~"Chart the B'Tran Cluster"~ to earn an easy 2880 D. This should take about half an hour to complete.

• The security officer on ESD/Qo'nos/DS9 lets you turn in 3x 5x Contraband for an easy 2000 D. If you have Contraband or spare energy credits to purchase them on the exchange, you can do this every two four hours.

• Elite STFs reward 960 D each time and take about half an hour each to complete. You also get Borg Neural Processors, which can be traded at a rate of 5 BNPs = 1000 D through the reputation system (but it is highly recommended that you save your BNPs to purchase Mk XII gear at Tier 5 Omega rep).

• Starfleet Academy and KDF Academy have a midterm daily which you can use to quickly grab 480 D. This takes less than a minute and you can guarantee your success by using this page (Interactive Path to 2409).

That's a pretty routine run for me when I'm trying to hoard dilithium. What are your strategies?

Edit: forgot one!

Edit 2: as of Season 6, Turn Over Contraband now requires 5 instead of 3 contraband, and has a four hour CD instead of a two hour one.

Edit 3: as of Season 7, Elite STFs now reward much less than before since Borg tech/salvage and EDCs no longer exist, and "Chart the B'Tran Cluster" no longer exists.
