What type of crime is doxxing?

Could you please explain what type of crime doxxing is? I've heard it mentioned in relation to cryptocurrency and finance, but I'm not entirely clear on its legal implications. Is doxxing a form of cyberbullying, identity theft, or something else entirely? And how does it specifically relate to the world of cryptocurrency and finance? I'd appreciate a clear and concise definition of the crime, as well as any potential consequences that could arise from engaging in such behavior.
