What is a good DPI number?

Could you elaborate on what DPI stands for and why it's important when it comes to financial investments, especially in the realm of cryptocurrency? How does a higher DPI number compare to a lower one, and what factors should one consider when determining what constitutes a "good" DPI number? Is there a specific benchmark or range that investors tend to aim for, and if so, what are the potential consequences of falling outside of that range?
