What does Coinbase global do?

Could you please elaborate on the role and operations of Coinbase Global? I'm particularly curious about their services in the cryptocurrency industry and how they contribute to the global financial landscape. I understand they are a major player in the crypto sphere, but I'd like to know more about their specific offerings, their reach, and the impact they have on the broader market. I'm also interested in their regulatory compliance and how they ensure secure transactions for their users. Any insight you could provide would be greatly appreciated.
