Arthur Hayes, co-founder of BitMEX, recently sold $8.4 million worth of Ethena (ENA) tokens shortly after praising the cryptocurrency, which led to speculation about market manipulation. His endorsement initially boosted ENA's value by 25%, but the subsequent sell-off raised concerns about investor confidence. Hayes had previously unstaked and deposited millions of ENA tokens into Binance, and reports indicate he withdrew approximately $7.85 million in USDC from the exchange. As of now, he has about $9.08 million worth of ENA remaining after depositing $2 million into Bybit. Meanwhile, North Korean hackers have been reported to be active on the Hyperliquid platform, raising alarms about potential security threats, with reports indicating that they were responsible for over $700,000 in losses and stole $1.3 billion worth of crypto this year.
