What is a good yield rate?

I'm curious, what exactly constitutes a good yield rate when it comes to investments, particularly in the realm of cryptocurrency and finance? Is it simply a matter of comparing the interest or rewards earned against the initial investment? Or are there other factors that should be taken into consideration, such as the risk involved, the duration of the investment, and the potential for capital appreciation? How does one go about determining if a particular yield rate is favorable, given the volatility and uncertainty that often characterizes this sector? Is there a benchmark or standard that's widely accepted in the industry, or does it vary depending on the specific investment vehicle and the investor's individual goals and risk tolerance?
