What does pro service mean?

Could you please explain to me the meaning of 'pro service' in the context of cryptocurrency and finance? I'm curious to understand what services are typically offered under this umbrella term and how they benefit individuals or businesses involved in the industry. Is it related to advanced trading strategies, personalized financial advice, or perhaps a combination of multiple professional services? I'm looking for a clear and concise definition that helps me grasp the essence of 'pro service' in this particular field.
