Welcome to Chain Reaction, by Capital Copilot, your daily dose of the latest in cryptocurrency news, market insights, and blockchain trends. Let's get started! Bitcoin continues bleeding, Ethereum sentiment collapses, and Mark Cuban dumps his Bitcoin. Congress launches insider trading probes while Polymarket gets exploited. Bitcoin has crashed to approximately seventy-six thousand dollars, marking its lowest level since April twentieth and representing a drop of over ten percent from its peak earlier this month. Spot Bitcoin ETFs suffer massive outflows totaling two point two six billion dollars over the past two weeks. Rising Treasury yields are pushing investors away from zero-yielding assets like Bitcoin, with capital rotating into commodities and pre-IPO bets on SpaceX instead. Over five hundred seventy-five million dollars in leveraged long positions were liquidated. Ethereum is retesting support near two thousand twenty-nine dollars after an eleven point five percent decline earlier in May. According to analytics firm Santiment, Ethereum's bullish-to-bearish comment ratio collapsed from two-to-one to one-to-one. Multiple negative narratives are converging: underperformance versus other assets, massive ETF withdrawals, departures from the Ethereum Foundation, and competition from faster-growing ecosystems. Billionaire investor Mark Cuban sold most of his Bitcoin holdings, citing disappointment with crypto's failure to deliver mainstream applications. The divergence between gold and Bitcoin during the Iran conflict was the breaking point. Gold surged to five thousand dollars while Bitcoin struggled despite a weakening dollar. Congress has launched investigations into prediction market platforms Kalshi and Polymarket over insider trading concerns. House Oversight Committee Chair James Comer sent letters demanding internal records on identity verification and anomalous trading activity detection. Analysis found eighty bets on Polymarket with a ninety-eight percent win rate, statistically impossible without insider information. Polymarket suffered a security incident involving approximately seven hundred thousand dollars drained from internal operational wallets.

Grayscale filed its third amended SEC registration statement for a proposed Hyperliquid ETF, expected to trade under ticker GHYP. The filing includes new staking reward functionality, allowing investors exposure to both HYPE price movements and blockchain staking yields. NEAR Protocol's token surged twenty-eight percent over twenty-four hours to two dollars and twenty-four cents, driven by three major product announcements including Confidential Treasuries for private on-chain multisig and dynamic resharding arriving in June to scale to seventy-plus shards with Visa-level throughput.
