Using this context, create a currency which is a coin called Ion Crystals. Here is the context: A sleek, futuristic small fighter jet with a streamlined, angular design. The body features dark metallic tones with glowing accents in neon blue or green. The plane has retractable delta wings for enhanced maneuverability, integrated plasma engines with glowing exhausts, and energy-based weapons like plasma cannons and missile pods. The cockpit has a bubble canopy with a holographic interface. Dynamic features include hovering capability with glowing thrusters and deployable energy shields. The plane’s surface is detailed with subtle etched patterns and glowing energy conduits. Do not create the ship, only the coin based on that context. It should be glowing blue a lot. Only one coin.
