You can count on it that the dili/zen market will spike, crash and wobble from the fairly stable 300 it has been, so if you have the Ferengi Lobes for it you might even make a nice dilithium profit (hint #2).
So, buy Zen now and sell later? My lobes are so small..
Convert dili into zen now 🙂 After Season 14 goes live in a week or two I expect the zen/dili rate will drop then rise and drop again, maybe up to +320 for a few days. That’s asuming Cryptic follows its usual plan releasing a new ship (pack) that needs to be outfitted/upgraded (so higher demand for dili) and a new lockbox with another unique ship/item (lower demand for dili, but more for keys/ec).
I know there are some in the fleet that are very savvy dili/zen market-watchers, and if lucky enough you can make a nice profit.
