Is voxel free?

Excuse me, could you clarify for me? Are you asking if the voxel, as a unit of measurement or a term related to 3D graphics or virtual reality, is freely available for use without any cost or restrictions? Or are you referring to Voxel, a specific cryptocurrency or digital asset, and wondering if it can be acquired or traded without any initial investment? It's important to distinguish between the contexts as the answer may vary significantly. If you're asking about the latter, I'd need to check the current state of the cryptocurrency market and the specific rules and policies surrounding Voxel. Could you please elaborate on your question?
