Star Trek Online like many MMOs uses multiple in-game currencies. Reputation, fleet equipment as well as cosmetic items are purchasable using a variety of energy credits, dilithium and reputation tokens. Cryptic have therefore placed various restrictions governing these items to ensure that the game economy remains functional. However many players still amass sizeable quantities of these currencies overtime; especially those with multiple alts and sufficient time to invest in the game. At present although dilithium ore can be earned in multiple ways, a daily cap allows only 8,000 units to be refined each day. It is refined dilithium that can be used as a tradeable currency.
