What is the difference between CCP and XCP?

Could you please clarify the distinction between CCP and XCP for me? Are they both cryptocurrencies, or do they serve different purposes within the blockchain ecosystem? I'm particularly interested in understanding the key features that set them apart from each other and how their respective use cases might differ. Additionally, could you provide any insights into their adoption rates, market performance, and potential for growth in the future? Thank you in advance for your detailed explanation.
