The Cost Coin+ project still appears to be very active and in full swing. All the indications of a probable scam by this project creators points to null as it appears to be fully operational, integrating services but largely in the Chinese region. In my time trying to access the information about this project from it's website, I was limited to the use of simplified Chinese language on the platform which even my browser could not translate due to reasons I do not understand. This clearly indicates a heavy concentration of the project market in China.
From the little information available online, Cost Coin+ as an Ethereum based ERC-20 project claims to be a global blockchain project that connects services in the fields of travel, resort, and lifestyle and with the Outlook of things especially in regards with its trading volume on Probit exchange, I don't think they have achieved major success. What I feel about this project is that currently needs the support of its community to help bolster its functioalities and bring it to the limelight
As for my recorder notes on whether it legitimate enough to invest with, read the little information I have gathered so far, solely to the users who live outside of China, I don't think this project is good enough to invest with but as for those who live around the region of China and can confirm it reliability and partnerships, then all indications point to YES
