According to Golden Finance, Upbit issued an investment warning for HIFI tokens. Currently, HIFI has been included in the trading watch list by the Joint Negotiation Association of Digital Asset Exchanges (DAXA) and will suspend deposit services.
Once a digital asset is put on the watch list, Upbit will typically conduct a detailed review of the digital asset to decide whether to extend the watch list, cancel the watch list, or ultimately terminate support for the transaction.
