Create a cinematic, dark, high-end crypto channel intro. The scene starts in a deep black, slightly textured background with subtle fog and particles floating in the air. Slowly emerging from the darkness, highly detailed, realistic 3D cryptocurrency coins appear (Bitcoin, Ethereum-style coins, but abstract and generic, no logos required). The coins rotate in slow motion, illuminated by cold, sharp rim lights and soft reflections, giving a premium, elite, institutional crypto aesthetic. The camera moves smoothly and professionally, with slight depth-of-field, creating a cinematic feeling. An epic, dark, modern cinematic sound design plays in the background (deep bass, subtle risers, minimal but powerful). Towards the end, the coins fade into darkness. Then, the name “GROTH” appears as if being signed by hand, drawn smoothly across the screen in a clean, elegant, handwritten signature style. The signature glows subtly for a moment, then settles into a matte white or silver finish. The final frame holds on the signed name “GROTH” on a dark background, clean and powerful.
