On June 23, 2026, global stock markets suffered a synchronized sell-off: South Korea's KOSPI plunged 9.99% and triggered two circuit breakers, Japan's Nikkei 225 dropped 3.55%, China's A-share ChiNext fell 3.84%, and U.S. equity futures tumbled over 2% pre-market. The root cause lies in the AI trade shifting from "valuation expansion" to "earnings validation" – SpaceX lost 31% in three days (four simultaneous blows: acquisition dilution, bond issuance, options shorting, and fundamentals collapse), Google dropped 5% on talent departure, compounded by Korea's leveraged ETF regulatory scare, pre-earnings caution on Micron, and Fed hawkish signals pushing the 10‑year yield to 4.49%. The bigger test for SpaceX lies ahead with insider unlock in August.

In June 2026, JuCoin was flagged for abnormal withdrawal processing, with reports that a significant portion of its reserves consisted of stablecoins issued on its own proprietary chain rather than official versions, raising doubts about reserve transparency. The platform has undergone multiple rebrands, previously suffered losses due to contract vulnerabilities, and has heightened user vigilance regarding exchange security. CoinW, in contrast, has maintained an eight-year track record with zero security incidents. It employs multi-signature technology, MPC-based private key sharding and distributed storage, full-stack risk controls with real-time monitoring, and a publicly verifiable Proof of Reserves (PoR) mechanism to ensure transparent and auditable asset backing. Users are advised to self-check withdrawal conditions on their current platforms, verify PoR, assess operational history, and consider migrating to CoinW, where completing KYC enables secure trading.
