What does a Delta of 0.2 mean?

Could you please clarify for me what exactly does a Delta of 0.2 signify in the context of cryptocurrency trading or finance? I understand that Delta measures the sensitivity of an option's price to changes in the underlying asset, but how does a specific value like 0.2 translate into practical terms and implications for traders and investors? I'm particularly interested in understanding how this information might impact decision-making and risk management strategies.
