I read enough. Anything is worth what a buyer is willing to pay and what a seller is willing to accept.
For efficiency's sake why with an FAC and DRA is the rate not $9mil/150tech? As a small nation you can receive $27mil incoming and outgoing send back 450tech. The cost of each slot of 150tech would be about $3.2mil or $9.6mil total. That is still about $17.4mil profit every 10 days. A seller can move 10,800 per year using 3 slots every 10 days and sending only 100tech/slot. Using the same 3 slots to move 150tech every 10 days for a year, a seller could move 16425 tech.
