What is a good ROI?

Good day, I'm curious about something. Can you help me understand what exactly is a good ROI, especially in the context of investments in cryptocurrency and finance? I've heard the term quite often but I'm still not entirely clear on how to measure or determine what constitutes a "good" return on investment. Could you elaborate on the factors that influence this metric and maybe give some examples of industries or projects that have historically demonstrated strong ROIs? I'd really appreciate your insights on this matter.
