The Coinmarket and Coingeco's networks are an essential part of all the marketplace. They really provide all the necessary information about a project that no other official page would have. It is in this way how I trust the content they offer to know that Krobot is already a non-existent project. If users look for it, they will find anything.
The project had not so many users in the beginning. It was designed as part of an experiment to measure if the scope grows as fast as it was though. However, that did not happen. The project did not receive more support and management, and it is currently unavailable. At least its web page is out of service.
Users can still look for it in the markets I mentioned before. I suggest checking for yourself the current status of the company by accessing those legit markets. But remember not to invest in anything risky to your data or the health of the devices you use.
Note: Korbot's token is called Kbot, and it still has an updated price in the different markets. Do not try to acquire the token, but it does not serve to invest in anything.
