I'm pretty out of it (obviously), and I was never really good at this part of the game anyways, so I'll ask:
How do I make money? I know there's a bunch of guides on how to get dilithium, and they pretty much all say the same thing, so that's not really my concern. No, I want EC.
I gather the key is getting stuff to sell on the Exchange (recycling equipment doesn't seem to be cutting it). But what do people buy? Just purples, or are greens (or even blues) good too? I'm max level on both my characters, so it's mostly a factor of getting good drops, right?
Just running 20 DOFF assignments a day will provide you with some Dilithium, ECs, DOFFs, BOFFs, consoles, weapons or equipment. Sell what you don't need on the auction. Just try to plan the assignments so you have a good chance at critical success. You won't get rich quick, but you'll make a decent income.
