What is a good yield on cost?

Excuse me, could you clarify what you mean by "a good yield on cost"? Is this a term specific to the world of cryptocurrency or finance in general? I'm curious to know what factors one should consider when determining if a yield on cost is considered "good." For instance, does it depend on the type of investment, the current market conditions, or the individual investor's risk tolerance and financial goals? I'd appreciate any insights you could provide on this topic.
