What is the difference between CTO and CIO?

I'm curious about the distinction between CTO and CIO. In the world of cryptocurrency and finance, both of these roles seem to play important parts in driving innovation and managing technology. Can you explain the key differences between the Chief Technology Officer (CTO) and the Chief Information Officer (CIO) roles, and how they may specifically relate to the industry we're in? Understanding their unique responsibilities and focuses could help me better appreciate the strategic value they bring to a company operating in the cryptocurrency and finance space.
