According to the Upbit announcement, ForTube (FOR) has been designated as a warning stock and the corresponding deposit service will be suspended. It stated that the issuance volume of ForTube (FOR) seems to have exceeded the situation, and has repeatedly asked the foundation to explain, but the foundation has not responded. In addition, according to the best practices in supporting virtual asset transactions, considering the large-scale changes in the business, the transparency and rationality of the change procedures, the actual progress of the project and other important matters, the project is not sufficient. Therefore, Upbit designated ForTube (FOR) as a warning stock to protect investors.
