What is a good take profit percentage?

Could you please elaborate on what constitutes a "good" take profit percentage in the context of cryptocurrency trading? I understand that traders often set targets to exit a position once a certain profit level is reached, but is there a general rule of thumb or a specific range that is widely accepted as optimal? Does this percentage vary depending on the type of cryptocurrency, the market conditions, or the individual trader's risk appetite? And how does one determine the most suitable take profit percentage for their own trading strategy?
