Upbit said the situation was under review and the exchange could take protective measures, including warnings, trading restrictions or ending support if necessary. Users holding FLOW are advised to be careful.
This announcement follows a sharp drop in FLOW earlier today. The asset fell from above $0.17 to around $0.1, its lowest level since launch, according to CoinGecko data. FLOW once traded as high as $42 at its peak.
Meanwhile, the crypto market continues to struggle, with Bitcoin still unable to reclaim the $90,000 mark. Analysts remain cautious and see limited upside potential in the short term.
