As of my last knowledge update in January 2022, "Rollbit" doesn't refer to any well-known or widely recognized cryptocurrency or blockchain project. Cryptocurrency projects emerge frequently, so if "Rollbit" is a newer coin or token that has come into existence after that time, I might not have specific information about it. Always conduct thorough research and due diligence before investing in any cryptocurrency, especially newer or lesser-known ones, to understand their purpose, technology, team, and potential risks involved.
