Deuterium → Crystal
Exchange rate
Exchange at the Merchant: 1 Deuterium → 2 Crystals.
Base rate from the game code: 1 Deuterium yields 2 Crystal; a payout coefficient of 0.95 is applied (a 5% fee), so effectively 1 Deuterium → 1.9 Crystal. For example, 1,000,000 Deuterium turns into 1,900,000 Crystal (the engine rounds the result down). This pair has no fixed volume cap — the per-transaction maximum depends on your Spaceport capacity. The reverse pair "Crystal → Deuterium" trades at a base rate of 1 → 0.5 (payout coefficient 0.95); a round trip returns ≈90.25% of the volume, losing ≈9.75%. The exact in-game rate may differ: the engine adjusts it to demand and trade volumes, while the fee always applies.
The exchange is available at the Trader. The base rate is set in the game code; the actual rate shifts slightly with demand and trade volumes. Dark matter exchange is limited by the amount per operation.
