How much is a micro stock?

Excuse me, I'm a bit confused about the concept of 'micro stock' in the context of cryptocurrency and finance. Could you please elaborate on what it refers to? Specifically, I'm wondering about the value or pricing mechanism behind such a micro stock. Is it a fractional ownership of a larger stock, or does it represent a specific cryptocurrency token? Additionally, how does its price compare to traditional stocks, and what factors influence its valuation? Your insight would be greatly appreciated in understanding this niche market segment.
