What category is ASD?

Excuse me, but could you clarify what exactly ASD refers to in this context? Is it referring to a specific financial term, a type of cryptocurrency, or perhaps a more general abbreviation for something else entirely? Understanding the full meaning of ASD is crucial to properly categorize it, so I'd appreciate it if you could elaborate on its definition. Once we have that information, we can then discuss the appropriate category for ASD, whether it falls under finance, cryptocurrency, or some other sector.
