You were interested enough to be reading it; so... ;)

As Tanki expands I'm sure they'll introduce new currencies to buy crystals that previously were not available. But I'm not sure of teh time period I'm afraid

Quick question that has been bugging me for a while. How do you work out how much crystals is worth a certain currency. As it is an in-game currency that has no value in real life?

Surely if the difference is a mere few thousand crystals. The Tank Owner could just play to earn it ;)
